When Edward and Larry are arguing over the identity of Andrew Dice Clay (Fonzie vs. Bowzer from Sha Na Na), Larry says he knows it is Bowzer because he first saw Sha Na Na at Woodstock. Greg says that there was no way that Sha Na Na was at Woodstock. Sha Na Na actually did play at Woodstock, as the penultimate act just before Jimi Hendrix. However, Jon 'Bowzer' Bauman was not present as he did not join the group until 1970.
