Wow, I don't see that at all. Bob Saget is horrible, corny, and not really that funny at all, like you said. Tosh on the other hand is, in my opinion, quite the opposite. I just love how anti-PC and offensive he is. He just doesn't care and that's what makes him funny. He's not afraid to make your parent's cringe. If he is copying anyone, it would be like he is Joel McHale's nastier little brother...
I think he's funny as hell.
