And there was this conversation in Irresponsible:

John: My childhood hero was Evel Knievel.

Teyla: Was he not evil?

John: No, it was just his name. He was a daredevil - which isn't kind of a devil. He just jumped motorcycles over things.

Ronon: Why?

John: Just because. Didn't always make it either.

Teyla: And you greatly admired this behaviour?

John: No, I just - look at least my hero is human. McKay's is Batman.

Rodney: Hmm. Misunderstood and unappreciated by many, because his most formidable weapon was the power of his brilliant mind. Not just a hero - a superhero.
