Double Naught Spy
Sus Venator
But the fact that his reason was because of pressure from the anti-gun crowd... I stand by the "no 'nads" comment.
Jay Leno isn't in the nads business and I am pretty sure whether or not you or anyone else thinks he has nads over this issue is truly of little concern.
Either the NSSF had a poor contract with Leno that allowed for him to back out (which is likely), or they will sue him for failure to perform. If the former, then the agreement was only tentative. As such, if Leno felt this was bad for his reputation, then he did the right thing.
