Character mistake: Loren mistakenly calls each pitch at the batter's mound a strike, when that is when a pitch is out of batting mounds, or the batter misses. A ball is when the batter ignores the pitch or doesn't make a swing.
Suggested correction: A player doesn't have to swing for a pitch to be a strike. He called them correctly.
Well unless I've missed something over the years in baseball... and Loren's obvious confusion on what to call... when a batter remains stationary during a pitch, that is a standard all-out ball. When the batter moves or swings and misses the pitch, it is a strike.
His initial hesitation had nothing to do with it being a bad call. And yes, you've missed a lot over the years. A batter can move or even check swing and still the pitch could be called a ball. When a batter remains stationary, that doesn't change a strike into a ball just because he didn't swing or attempt to swing. The poem "Casey at the Bat" is all about him not swinging on the first two pitches, and they were both called strikes.
Factual error: None of the Swedish wedding traditions Ingrid mention actually existed in the 19th century and the bread she's baked is not traditionally Swedish. When she later speaks in her mother tongue it's definitely not Swedish.
Factual error: In the later seasons (4-6) all the characters keep referring to their location as 'Colorado Springs' instead of just stating 'here'. Example: "I told him to stay in Colorado Springs" instead of just stating "I told him to stay HERE"
Continuity mistake: When Dorothy is doing laundry, she grabs a large piece of linen from the washtub, as Dr. Mike approaches and they talk about Dorothy hiring a caregiver for Loren, during his stroke. As Dorothy starts cranking the linen through the wringer, she stops to protest to Dr Mike about it but then turns around holding the wrung linen in her hand, though she hadn't finished cranking it out. (00:32:30 - 00:33:20)
Fifi's First Christmas - S4-E12
Continuity mistake: After Fifi has gone after the red scarf, Brian picks it up. In this wide shot, there is nothing on the left of Brian, however in the next close-up shot, there is a horse next to him.
Continuity mistake: When the whole town comes to support Matthew, we can see Hank and the reverend walking up behind him. A few seconds later, we see them both again, now they're walking with Colleen and Brian, and they have just come around the corner to see what all the fuss is about.
Visible crew/equipment: You see an automobile's headlights driving in the background when Hank is giving Dr Mike a hard time after his NaNa is brought to the clinic.
When a Child is Born (2) - S4-E28
Other mistake: Not to sound rude, but Jane (Seymour) was literally pregnant, in labor when her water broke, but no visible staining on her gown or on the wagon seat when Sully pulls her up.
Other mistake: Toward the end, when Mike is snuggling at the window with Sully, the candle on the wall near them isn't lit. But there is ominous light about them, obviously from the studio set.
Character mistake: As Preston is calling Sully on the sheriff situation, Loren enters, brandishing a new rifle to Preston, almost right over the baby's carriage. No way in tomorrow would Dr Mike or Sully have allowed this to happen, but have aimed the firearm in another direction, or at least Sully move in front, away from the baby's carriage.
The Tempest - S5-E10
Other mistake: Smoke from the burning Thanksgiving dinner starts wafting from the stove just moments before a strong wind from a coming storm blasts through the window. Yet somehow Michaela doesn't notice the smell just moments before going outside with Katie.
Other mistake: When Sully's wrist gets scraped while moving the examining bed off the wagon, Dr. Mike merely dabs over it with some disinfectant, instead of thoroughly cleansing the wound with a wet cloth before suturing like a normal doctor.
Continuity mistake: The gown Gilda S. Claire wears at her open concert is not the same one Emma made for her in the Mercantile.
The Comfort of Friends - S6-E4
Continuity mistake: When Michaela enters the homestead after handing Katie off to Matthew, it immediately cuts to her in the master bedroom upstairs, pouring water into the bowl to splash on her face, as she suffers another pregnancy attack when she wouldn't have been able to manage climbing the stairs in her delicate condition.
Wave Goodbye - S6-E5
Plot hole: Dr. Mike and Daniel are discussing whether Princess Nizamoff is a fake or not, considering all the voices from the dead she performed during the séance. Yet Mike totally forgets that Mizamoff addressed her former medical professor in grave detail. Something the Princess would not have known otherwise.
Factual error: Marjorie's tragic death: The Quinn family has her funeral in the town cemetery, where she did not belong, instead honoring her death with a vigil, then transporting her body back to Boston, to be buried properly with her Quinn relatives: A common respect reserved for dignitaries; which technically the Quinn family was/is, and soldiers.
Plot hole: In the ending scene, Mike has a probable concussion from her fall, so Sully keeps her awake to prevent her slipping into a coma. They talk all night, reminiscing as Mike experiences periodic pain spasms. Their talk ends with discussion over them having another child, and then they instantly engage in an intimate moment, which would be impossible, considering her condition, and without further checkup from another doctor. Sometime later she is suddenly feeling 'cured', and they return home.
