It's odd that Slaters 'right' shoulder got hurt in the accident when he was sitting behind Zack (which means he would've 'whacked' his shoulder against Screech). It would've made more sense if it was his left shoulder, since it was against the door.
Mr. Morris: What would you do if you were in my position?
Zack: Tori, have you met Tara and Tami?
Tori: No, so far I've been lucky.
Mr. Belding: (explaining Screech's version of what happened in the accident to Lisa's mom) It's a terrible thing that happened to those monkeys though.
Zack's garage set is the same set used as the garage on sister show California Dreams, right down to the surfboards on the wall and the photo frame up the stairs.
Kelly and Jessie do not appear in this episode.
