Outstanding show, and as noted by other commenters, P&T actually wait out in the lobby afterwards to greet and take selfies with everyone who's interested.
NOTE: If you're an contributor/investor/someone who gave money for Penn's crowdfunded film "Director's Cut," be sure to wear the t-shirt to the show. Teller thanked me for supporting the film, and when Penn first saw me (even before I got to take the picture with him), he winked at me and mouthed "Love your shirt!". After the impersonal Jimmy Kimmel a few months before (check out my review of his show), P&T were a breath of fresh air and a reminder that being a celebrity does not have to make someone a self-involved diva.
