The Magic School Bus - Wet All Over

Arnold and Wanda are getting water for their waterworks project in the girls' bathroom. Arnold voices his concern of getting caught, to which Wanda teases, "Who's going to catch you in the girls' bathroom? Tiffany?" He denies knowing such a girl. As she takes the bucket of water back to the classroom, he stays behind, only to get caught by Tiffany, who runs away in shock.
