The Music Box (1932)

Continuity mistake: When Oliver falls into the fountain with the wooden crate, you can tell the crate is empty because it is floating. But when we see a close-up of Oliver in the next shot, the crate has been weighed down and is not floating.

Ollie: What were you doing up there?
Stan: I was trying to plug it in.
Ollie: That's not the place to plug it in! Give it to me.

Trivia: "The Music Box" won the first Academy Award for Live Action Short Film in 1932. It was also the only Laurel and Hardy film to be honoured with an Oscar.
