Other mistake: During the 3-nightmare sequences, there are 25 students, with all desks full. However, 1 desk should have been left open as Kevin appears in the dreams, meaning there should only be 24 students.

How I'm Spending My Summer Vacation - S2-E17
Plot hole: When Kevin is upset about Paul leaving for summer and is just lounging around the house, he asks why they can't go on vacation. His mom says "Maybe next Summer." In the very next episode, which takes place in the same Summer, they are going on a "traditional" Summer vacation.
Wayne Arnold: Butthead.
Question: Did this show have an episode in which Wayne was stood up by a date, or he couldn't convince a girl to go out with him? Then Kevin told him that the girl thinks he is pathetic. I described this moment in the "General Questions" section here, and someone said it might be this show. Thanks.
Answer: Sounds like the episode 'Hiroshima, Mon Frère', season 2, episode 8.
