"Super Mann" (Lois & Clark: The New Adventures of Superman, 3.09)

LOIS: [She reaches into one of the shopping bags and pulls out the world’s teeniest, tiniest bikini.] ...Bermuda.
CLARK: [Clark’s eyes widen at the image that comes to his mind.] Golly.
Superman III



This is just a theory, but I think Superman enjoyed being a smartass 

Clark is a little shit sometimes but it’s always good natured.
