The text is a play on the phrase 'the work of 3 men' which usually implies that someone is very productive. However, it is followed by the names Larry, Moe, & Curly, who are the three stooges known for their slapstick comedy and not for being productive. This creates a humorous contrast and relies on the recognition of the names for the joke to work.
He does the work of 3 men . . . . Larry Moe & Curly .
