The part where they say about playing a Beach Boys song 'California Dreamin' threw me the first time as I thought it was a misquote as this was best known by The Mamas and The Papas. Here I come to find that the Beach Boys actually recorded a version in '86 for a best of album.
Hah, I'll add another layer of humor - I actually thought it was an intentional mistake to illustrate that these were actually dumb kids (I say this as someone who was a dumb kid myself during roughly the same period) who didn't know who The Mamas and The Papas were.
I, too had no idea that the Beach Boys had covered it.
