"Oceans of Lotion" is the first challenge in the second episode of Season One, "Butterfly Crime Scene". The guys had a sunscreen kiosk at the beach and gave people free lotion. They had to apply as much lotion as possible because whoever applies the least loses.
Sal only applied 1/4 of his lotion, the least of the guys. The person who he applied it on ran away from him.
Joe got 3/4 of the lotion on.
