Whenever I see someone like Hoagland going back to the Galileo argument, I am reminded of an old Abbott & Costello skit (quote may not be perfect, I'm doing it from memory).

Abbott: That's crazy!!

Costello: Oh yeah!! Well, they called Galileo crazy! They called Columbus crazy! They called Raymond Strumeister crazy....

Abbot: Wait, wait, who is Raymond Sturmeister?

Costello: Oh, he's my wife's second cousin <whispers> frankly, He is Crazy!!
