Continuity mistake: During the song "Ain't Got Rhythm" Swampy's earring switches ears between shots.

Candace Loses Her Head - S1-E7
Continuity mistake: At the starting of the episode when Phineas wakes up you can see right next to him there are two pillows on his bed but when he sees the calendar and is about to throw the pillow on Ferb you can see that there is only one pillow.
Continuity mistake: When Phineas, Ferb, and Candace go to the stairs, the door has 'stairwell' written on it. Then, when the bubblegum case falls, before it goes through the door, it reads 'stairs', but once the door is open, it's back to 'stairwell' again.
Dude, We're Gettin' the Band Back Together! (Part 1 & 2) - S1-E22
Continuity mistake: During the end of the episode, Phineas is video taping his parents, but what he is recording is a different angle that what is being shown on the screen. From Phineas' angle, the camera is only showing the back of his mom's head. However, the big screen above the band shows that the camera angle can see both of his parents' faces.
Day of the Living Gelatin!/Elementary, My Dear Stacy - S2-E6
Continuity mistake: In "Day of the Living Gelatin" when you first see the TV in Perry's lair, the letters MM are visible on Monogram's jacket. In the close-up they are gone. (00:04:40)
Continuity mistake: In the episode "Don't Even Blink", during the song segment, Phineas changes from playing the guitar lefty and righty several times.
Continuity mistake: In the episode "One Scare Ought To Do It," when the haunted house comes back, it is stuck to the Disinvaporator. The clock says 5 seconds left, but when it cuts to the closer shot of the clock, it lost 3 seconds, which means that 2 seconds are left.
Continuity mistake: One of Ferb's eyes is egg-shaped while the other is normal. Whenever he turns his head, the egg-shaped eye is always furthest away.
Invasion of the Ferb Snatcher/Ain't No Kiddie Ride - S2-E28
Character mistake: In 'Ain't No Kiddie Ride' Carl reminds Major Monogram that he has no sense of smell and that he was born without nostrils noting it on his resume. But in 'Brain Dead' when Major Monogram sees Perry wearing a face mask he points out that Carl is also a germaphobe. Carl corrects him saying "It's not the germs sir, it's the garlic smell." He wouldn't be able to smell anything since he has no nostrils. (01:10:00 - 01:35:00)
Other mistake: The small door Candace enters at the beginning leads to the living room when really, it should be the kitchen. This error was not fixed in "Rollercoaster: The Musical."
Flop Starz - S1-E3
Continuity mistake: During the flashback to when Linda was Lindana, a mark can be seen on her right cheek but in the shot of her in the elevator and the newspaper saying she's back, no mark is visible. Also, her hair bow is on the wrong side.
Got Game?/Comet Kermilian - S1-E30
Continuity mistake: Candace is wearing a white crop-top and dark blue jeans in this episode, but when she goes to get ice-cream and because of Suzy falls into the cart, the cart begins moving and crashes into the tree. When Candace raises her head and upper torso out of the cart for a brief moment, she is wearing her usual red dress. But in the next shot, however, she is wearing her white crop-top and dark jeans again.
Continuity mistake: Candace's neck is being measured in length for the fashion show, and an assistant is using measuring tape very close to her. In the next shot, he has completely vanished.

Continuity mistake: You can see Candace hugging Phineas. But in the shot directly after that, they're no longer hugging.
Operation Crumb Cake/Mandace - S4-E21
Other mistake: When the reverse-inator zaps Phineas, and he takes apart the sculpture, it is impossible that he took down the whole thing alone, because he didn't build it alone.
Answer: "One boring day, Phineas recognizes an important truth; Summer vacation will end, and the teachers will want to know what they did on their summer vacation. And with these two kids, it has to be something extravagant..."http://uk.imdb.com/title/tt0852863/.
