Continuity mistake: Lamar's javelin that he's seen running with is flexible in the middle and not very rigid, however when the shot after he throws it, we see a solid normal javelin going through the air and visibly a different one altogether. (01:06:30)
Suggested correction: It is a specially designed javelin by aerodynamics master Wormser.
Continuity mistake: At the skit competition, the RHO class is in a boat with the waves moving. They stop moving their oars when the sorority girls pop their heads up. The waves continue to move while the girls are briefly singing, even though the guys are not moving their oars. However, after the girls go back down, the waves have stopped, and only move again when the guys move their oars.
Suggested correction: There is no evidence at all that the oars are moving the waves. It is more likely some people offscreen are doing it.
