Leave It to Beaver S05 E08 Wally's Big Date

"Gee, Wally!"

Wally's school is having an exchange dance and Wally and Eddie must take girls from a rival school that they chose out of a hat. Eddie asks to trade with Wally and he agrees, like a shot, after seeing the picture of Eddie's intended in a yearbook. Suspicious, Wally soon quickly discovers why Eddie wanted to trade; the girl is a few inches taller than Wally.
