Good Night, Dear Heart - November 9, 1957 - S2-E17
Audio problem: When Sam and the Sheriff are on the dock the Sheriff is talking through a shot into the next one, except his mouth isn't moving during the last seconds of his line.
Pool Hall Blues - September 4, 1954 - S2-E18
Factual error: After Eddie tells his helper to get rid of Sam's/Charlie's pool cue Alberta, we see an exterior street shot with an elevated subway going by, with a lot of 1970s and 1980s cars parked and driving by. Not quite appropriate for the 1954 setting. (00:35:40)
Pool Hall Blues - September 4, 1954 - S2-E18
Revealing mistake: After Al comes back when the power is turned on, Sam wins a game, breaks for the next and then we see a wide angle shot and the noise is made when Al shows Sam where to shoot. But the beam doesn't appear, even though the shot is seen by viewers.
Pool Hall Blues - September 4, 1954 - S2-E18
Continuity mistake: After the bad guy tries to hit the granddaughter with the pool cue, Sam grabs it. In the wide angle shot it shows Sam's left hand about 6-8 inches from the middle (where the dark wood inlay is), but in the next close-up shot, his hand is only about 2 inches from the middle.
Leaping in Without a Net - November 18, 1958 - S2-E19
Visible crew/equipment: When driving to Denver we see the trucks with trailers go around a curve, and two modern cars are briefly visible on the right along with the knee of a crew member. The cars are probably the parked cars of the camera crew. (00:36:25)
Leaping in Without a Net - November 18, 1958 - S2-E19
Audio problem: In the beginning of the show, when Sam's father tells him to get down, Sam climbs down and falls off the net. When he hits the dirt it makes a sound like he's hitting a board.
Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: When Sam and his sister are on the trapeze and she does a double and he catches her you can see that the bar she jumped from is not moving behind her. Then when she jumps back to it, it's swinging again.
Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: In practice, when Sam's sister tries to do the triple and he misses her, the wide angle shot shows that she is already below Sam's arms when she reaches out. But when it cuts to a close shot, she is able to almost catch his arms.
Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: Throughout the show, the big top changes from one with many blue stripes on the ceiling, to one with a couple of blue stripes and a dark center, and back again.
Maybe Baby - March 11, 1963 - S2-E20
Factual error: At the beginning when escaping, the song playing on the radio in the truck is "My Boyfriend's Back" by The Angels, which was released in July 1963, four months after the episode's date of March 1963. (00:04:00)
Maybe Baby - March 11, 1963 - S2-E20
Audio problem: When Sam is looking in the mirror talking to Al, he says, "Would you look at me? I've got a gold tooth." However, the reflection doesn't mouth the first part and doesn't even say the second.
Maybe Baby - March 11, 1963 - S2-E20
Continuity mistake: At one point when the police are chasing Sam, the car has a Sheriff's star on the driver's side door; however, when Sam drives into Clayton, no star is to be seen.
Maybe Baby - March 11, 1963 - S2-E20
Continuity mistake: When Sam is talking to Al in the store (while looking at car seats), Al checks on Margaret Dalton and holds the handset at chest level. The shot switches to Sam down on his knees and it's at his face level (about Al's waist). Then the shot switches back to Al and the handset is again chest high.
Maybe Baby - March 11, 1963 - S2-E20
Factual error: "Dancing in the Streets" by Martha and the Vandellas plays while the characters are driving. The problem is, the episode is set in 1963. That song was released in 1965.
Maybe Baby - March 11, 1963 - S2-E20
Factual error: Across the street from the general store where Sam and Bunny escape is an AllState Insurance office. The logo for the store is the more modern 1990s logo. The 1960s AllState logo had a different appearance.
Sea Bride - June 3, 1954 - S2-E21
Audio problem: When the little girl is dragging her sister across the room to get her to meet Sam at the pool, she says, "He's waiting at the pool for you," but her mouth doesn't even come close to mouthing those words.
Sea Bride - June 3, 1954 - S2-E21
Revealing mistake: At the beginning of the show they go to great pains to show (on more than one occasion) the "reflection" of Sam in the mirror. However, when the girl shoves him against it, kissing and slapping Sam, it is his real reflection.
Sea Bride - June 3, 1954 - S2-E21
Continuity mistake: At the end when Sam punches out the bad guy, there is not a white piece of trash stuck to the back of his left shoulder. Two shots later, there is a white piece of trash there.
M.I.A. - April 1, 1969 - S2-E22
Factual error: Though this episode takes place on April 1st, 1969, a freshly-painted sign in the park contradicts the date. In the scene with the hippies in which Sam is disguised as a meditating guru, the huge sign just behind him touts the San Diego Centennial Celebration - in 1968. (00:16:00)
M.I.A. - April 1, 1969 - S2-E22
Continuity mistake: In the beginning, when dressed in drag, Sam has a cigarette with a long bit of ash on it. He looks at his "reflection" and there is a short bit of ash on the cigarette, then it cuts back to him and there is a short bit of ash.
Chosen answer: Per the Quantum leap page at http://www.scifi.com/quantum/episodes/season5.html. 8 August 1953: An enigmatic leap lands Sam in a Pennsylvania tavern, as his own grown self on the day of his birth. As Al and Gushie work frantically to locate him, Sam befriends a wise bartender (popular character actor McGill, who'd appeared in a different role in the very first "leap") and a group of coal miners. As a host of familiar-looking faces pass through the bar - with different identities than Sam remembers - Sam ponders his life of leaping with Al the bartender, who tells Sam he controls his own destiny. Pressed for more, Al the bartender simply shrugs and says, "Sometimes, 'that's the way it is' is the best explanation." Sam realizes he must right at least one more wrong before he can go home, and leaps back to tell Al Calvavicci's wife Beth (from "M.I.A.") to wait for Al, who will survive Vietnam and come home to her. The closing title cards state that Beth and Al have four daughters and will shortly celebrate their 39th wedding anniversary ... and that Sam Beckett never returned home.
