Other mistake: At the end of Marge's video message to Homer, Marge explains she taped the message over their wedding video. The video then shows the remainder of Homer and Marge's wedding. This is inconsistent with The Simpsons' Season 3 episode "I Married Marge" and Season 8's "A Milhouse Divided," which show Homer and Marge marrying at a chapel on the state line and later Homer and Marge alone eating cake together in a parking lot.

Other mistake: After Mary has a tin of paint tipped over her head she runs out of the school, gets on the back of Slater's motorcycle, and they ride to the pool. Mary is covered in wet paint yet none of that paint is transferred to Slater's jacket. The back of the jacket is shown clean.
