Slackers (2002)

Continuity mistake: In the scene just following the opening physics exam we see the guys sitting smoking a joint and talking to Philip, the one they are paying to write the test. In one shot Sam hands Philip the joint and Philip says something about them doing better on tests if they stopped smoking pot. The shot changes to Sam speaking and he still has the joint. The shot changes to Philip and he is just handing the joint back to Sam.

Long-Haired Hobo: I'm not gonna eat that shit, you fuckin' retard.
Ethan: No one calls me a retard, ya freakin' hobo.

Question: When the movie shows the two at the pool jumping in, from where do they jump off? I didn't see any diving board at the pool.
