The Class Gets Frozen Yogurt

S1 E5: Ethan is mortified when Kat asks for multiple samples of frozen yogurt without ever placing an order or paying--and then dares him to do the same. After questioning her behavior, Ethan is forced to prove that he is not a wimp. Meanwhile, Lina struggles with her first day back at the office when she's unable to maneuver in her wheelchair. Feeling responsible, Richie hires Duncan to build wheelchair ramps for Lina's home, and as the guys bond, Duncan offers something else to help Richie out. Also, Kyle continues to have trouble dealing with Holly's intense desire for her daughter to attend the private school where he teaches.
