I'll Take Vanilla refers to young Tommy Bond's preference for ice cream flavor and the spoiled young man is driving his aunt Betty Mack to her wit's end trying to please him while she's babysitting.
Into their lives drives Charley Chase with his ice cream truck and while the tow of them hit it off, the hapless Charley gets sucked into their lives as another babysitter while Mack goes off to get a prescription filled.
While Charley is babysitting Tommy he happens to swallow a whistle which gives his voice a rather peculiar quality that's good for several laughs. When Mack doesn't come back, they go off in Charley's truck looking for her.
But when she does come back, she panics when she finds Chase and Tommy not home and calls the cop. The cop she gets is Harry Bowen who must have graduated from The Police Academy back in the day and might have been David Graf's great grandfather. Bowen gets almost as many laughs as Chase does in their scenes together.
It was not a good day for Charley Chase on his ice cream route that day, but it was a great day for the Hal Roach studio when they turned out a very good comedy short.
