College girls are easy
Zack meets a desperate 35-year-old "college student" at the Max, and she takes him and the guys to the club where all the desperate 35-year-old "college students" hang out. And what do you know? They run into The Sketchinator, cheating on Kelly! What are the odds? Of course, Zack fails to consider the fact that his mom is also part of the over-35 set, and therefore the odds that they're going to get busted are quite good as well.
