Always mentions he gets carsick? Can you name the times.

It's Whitey, and right away I think of the Lifeguard episode, where he even said thanks for stopping and giving him air. There's probably another instance, but I can't think of it.

Right. In Beaver Becomes a Hero he said he spent his weekend driving to Bellport and got carsick. In Beaver’s Bus he says he’ll need to sit in the front because he gets carsick.

I vaguely remember the Hero reference. But in school bus that quote is in the classroom after Miss Landers made the announcement about the bus transportation starting. I think he asks her if he can sit in the front, and she says Mr. Crawford will handle it, or something like that.

Yup and later in the corridor and Judy says Whitey is lying about getting sick.
