S02E20: Beaver's Pigeons

Beaver, Larry, and Whitey begin a pigeon club and they each purchase pigeons of their own. Beaver names his two Miss Canfield and Miss Landers, after his two teachers. However, when Beaver comes down with chicken pox, Wally is forced into caring for them, but soon finds Beaver isn't the only one ill - Miss Canfield and Miss Landers are also ailing.
