When Jack bursts in on Tracy in his white woman make up, Tracy waves at him with a monster claw covering his right hand. Seconds before, when Liz pointed out that he was wearing the claw (which Tracy attributes to them running out of make up, since he insisted they also do his buttocks) it was on his left. When Tracy had walked up to Frank and Toofer earlier, there was make up on his right hand and he hid his left from view.
