When Mu Gamma Xi first confronts Theta Nu Theta in the yard, a banner declares the Wolves as 2006 champions. Later, when DJ joins the pythons, his pledge jacket says "Spring 06."

When Sylvester wants DJ to lead the step at nationals, DJ tells Sylvester that he has waited for four years to beat Gamma Mu. In earlier scenes we can see that DJ has on a pledge jacket that says Spring 06 and Sylvester has one that says Spring 04. If Sylvester waited four years then his pledge jacket should have said Spring 02.
