Small Plot Holes In 'The Simpsons' Fans Noticed

From Redditoru/Gundamsarecool:

Found two Moes

From Redditoru/DCtimes:

An interesting plot hole. In “Homer The Heretic” (S04E03), the house catches fire while Homer is alone; the family is at church. Ned Flanders saves him, incredibly, skipping church. C'mon!

From Redditoru/Sippio:

Homer learns Marge is pregnant with Bart after seeing pictures of Lisa on the wall.

Froma former Redditor:

Smithers appears the same age as Homer and Barney in “Bye Bye Nerdie.” However, in “The Blunder Years,” he is a baby while Homer is a pre-teen.

From Redditoru/MassKhalifa:

Santa’s Little Helper appears in the "Barbershop Quartet" episode even though Bart is around 2 and 10 when they adopted him.

From Redditoru/Tourgott:

After all these years, I just noticed Marge had no problem flying in 8F01.

From Redditoru/WalrusJack:

If Poochie died on his way home planet, how could he show up at Scratchy's funeral?

From Redditoru/FictionVent:

S05E02: Does this mouse (that lives in the Simpsons' home) show up anywhere else in the series?

Aformer Redditoradded:

I wish I could find the reference, but I read Matt Groening wanted a parallel story of mice living in the Simpson home. That would have been an interesting idea.

From Redditoru/fentkentwick:

Lisa had friends and then she lost them.

From Redditoru/WalkingDeadArt:

I thought Nelson's father left him, yet he appears in season 6 episode 7, “Bart's Girlfriend.”.

From Redditoru/iwasAfookenLegend:

Gerald Ford can be seen driving a car inThe SimpsonsEpisode 141, "Two Bad Neighbors." Ex-Presidents cannot drive on the open road. The JFK assassination started this idea.

From Redditoru/scarface910:

This is either a continuity error or Edna living up to her character...

From Redditoru/Voxael:

I usually ignore continuity errors in the show (after all, a wizard did it every time we saw something like that), but this one always annoys me because it claims to be a photo of him at that exact moment.

From Redditoru/Danarky:

Found this little continuity error in “Homer's Barbershop Quartet.”
