the second form of the character MC Peepants(from Aqua Teen Hunger Force) who was once a six-foot tall spider bent on drilling a hole into hell. Now hes a cow with the same Bling and shower cap only now he sent by satan as a cow. Also now he must find a way to pay off hie rented patio furniture. But this time he is just sent to the slaughterhouse to die. quite hilarious.
Is Sir Loin coming back or have we seen the last of this high pitch voice character?
