Leave It to Beaver S04 E04 Wally, the Lifeguard

"Gee, Wally!"

Beaver proudly takes his friends Whitey and Gilbert on a picnic at the lake to see Wally in his first day as a lifeguard, not knowing that a new law forbidding anyone under age 18 from filling the position has forced Wally to work as a snack vendor instead. When he sees Wally in a floppy hat peddling hot dogs instead of sitting importantly on a stand in a lifeguard uniform, an embarrassed Beaver wants to go home before anyone else finds out.
