Opening Sequence

 * Mayan Mayor Quimby says that the destruction of earth would be Obama's fault, but how he know that there is going to been a president named Obama in 2012 even though is the 5th century in that time. But maybe because they are mayans they can tell the future.

The Greatest Story Ever Holed

 * Before Cletus's house is sucked up by the hole, you can see that the house is a double decker one (as you see that there is a window in the top of the house). But as the hole sucked it in, the hole didn't suck the second floor and the things in the second floor.

 * When the Simpsons are eating breakfast, they are in their pajamas. But when they open the door, they are in their trademark outfits.
 * Lisa says that what goes into a black hole never comes out, but then later Bart's math homework comes out after going in.

UNnormal Activity

 * In UNnormal Activity, Devil Moe says that Marge gets 30 years. 2012-30=1982; In there Marge is just a young child, but in Bart & Homer's Excellent Adventure she's already in high school. Hence the past time year Bart travelled to 1974. Meaning this episode is a non-canon.
 * Milhouse is seen sleeping in Bart's Room and Lisa's Room at the same time (Camera 6 and Camera 7).

Bart and Homer's Excellent Adventure

 * When Homer shows all the Historical Homers, Two Head Homer, Punk Homer, Egyptian Homer and Washington Homer are not on the line of Homers. But later they appear (maybe young Homer brought them after he brought the other Homers).
 * Just after Bart leaves the comic book store, Homer from 1974 is seen walking into a store next door.
 * Artie Ziff looks more different than in his previous appearance in Take My Life, Please.
 * Plot Hole: If Marge married Artie Ziff instead of Homer, then Bart, Lisa and Maggie shouldn't have been born (or, at the very least, look different from how they currently look), but this episode is non-canon.
 * Another Plot Hole: Homer and Marge are aparantly older than they look. Bart goes back to 1974 when they were still in high school. If this were the case, then they would be in their 50's in the present. (But again, this episode is non-canon and they don't age anyway.)
 * Marge says that 20 years ago, she would have chosen love when she realized that Homer was the one for her all along. However, 1994 is 20 years after 1974, and it is 2012, 38 years later.
