Corrected entry: At the beginning when Alfalfa is in the boat and the girl slicks his hair back, there is a shot where Alfalfa's hair is already up. When she kisses him, his hair pops up again.
Corrected entry: How does Darla find time to leave the recital, get changed, and be in the rich kid's pool before Alfalfa can get there running, when he left before the ballet recital was over?
Correction: Since the recital was over when the two left, Darla was supposed to have ridden with Waldo. So it seems logical she'd change into her swimsuit there. And it also, during the chase scene, gives you the idea that they have been running for awhile. So it is possible she had time.
Corrected entry: When Darla's friend says, "You're not thinking about Alfalfa, are you?" Darla replies, "No, no, no, no, no" as she says this, she looks right at the camera, and she also looks straight at the camera when all the girls say "Boys. Eurgh."
Correction: Not a real mistake.
Correction: Actually Darla pushes his hair down, right before she kisses him.
