This is from season 3 episode 11 - The Alternate Side.
George was charged with moving cars from one side of the street to the other while Sid goes to visit his sister. Sid comes back to discover many of his customers have cancelled on him because their cars got damaged.
Sid: Moving cars from one side of the street to the other don’t take no more sense than putting on a pair of pants. My question to you is who’s putting your pants on?
George: I put my pants on, Sid.
Sid: I don’t believe you. If you can put your pants on, you can move those cars.
George: Well I don’t want to get into a big dispute about the pants.
