Adam and Kristina Braverman's son Max has Asperger syndrome. So does "Amazing Andy" -- a bug expert played by Michael Emerson on 'Parenthood' (Tue., 10PM ET on NBC). The Bravermans hire the socially awkward man behind "Amazing Andy's Wonderful World of Bugs" for Max's birthday party. But Andy has some ground rules.

The maximum number of party guests: 25. "I have kind of a big family, and then his whole class is gonna be coming. So can you stretch that?" asks Adam. Nope. Another rule: "No clapping will be tolerated."

Kristina notes, "There's gonna be kids here -- there's going to be clapping." Andy says it is "very bad for the bugs." He then asks to use their bathroom and ends up taking a shower.
