"That's what Fran Tarkenton thought?"
OK, I just don't get the reference, and maybe someone can clarify what that line is all about.
After Dylan (Spade) takes the dog to Uncle Harry, who can talk to animals (Lovitz), Uncle Harry apprises Dylan that he knows that Dylan put the dog in the dryer. Dylan then says, "That's Incredible," to which Uncle Harry says, "That's what Fran Tarkenton thought." (And then he makes that stupid popping sound with his mouth.) Is this some obscure reference, or is there something about Fran Tarkenton that any 70's football fan should know?
