I think a better, already done topic, would be References in other shows to SB, because there really aren't that many tv show references. For a movie reference, the entire episode of Clams as well as Squeaky Boots, so I've heard. And then The Sponge Who could fly = The boy who could fly.
By the way, Mermaid Man and Barnacle Boy weren't exactly copied off of Batman and Robin, despite the title cards that come up and say stuff like POW, KING ME!, etc. They were almost exactly copied from Aquaman and Aqualad. They were pretty much the same characters except fused with Tim Conway and Ernest Borgnine in appearence.
