When Jake gets on the school bus, the Stevens house from "Bewitched" is across the street.
This episode reveals a laundry list of Charlie's fears. His fears are: germs, changing his looks, commitment, opening his eyes while underwater, angry husbands (was confirmed in Season 5's "Rough Night in Hump Junction"), angry ex-girlfriends, large birds (was confirmed in Season 1's "Big Flappy Bastards"), spiders and Evelyn Harper.
The scene in which Jake (Angus T. Jones) is pressed against the back door of the school bus is a recreation of the scene involving Waldo, in the Van Halen music video for "Hot For Teacher".
Episode title spoken by Alan, to Charlie.
