Factual error: Kevin and Wayne's bedroom shows a Beatles poster of the White Album. However this album, and presumably the poster as well, didn't come out until November 1968. This season opens with the summer and start of the school year 1968.
The Wonder Years (1988)
1 mistake in Season 1 generally
Starring: Daniel Stern, Fred Savage, Alley Mills, Dan Lauria
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.
