Penn and Teller certainly get one thinking... and one of the topics is \"Did I really enjoy the show?\"  They are very personable, connect and mingle with the audience (playing the bass in the pre-show or when they turn up the house lights), and convey their continued passion for the craft.  When they supposedly explained how something was done, I anticipated that the point would be that they would then do something inexplicable.  Maybe I just didn't get it, but I don't think they added a confounding twist... maybe I miss that touch of slickness.  I want to be wowed in a magic show, and the fire eating, flag burning (obviously more flimsy than the one they had folded), nail gun, and newspaper tearing just didn't do it.  I guess Penn's tour de force rants make the show transcend your typical magic show; I loved catching a glimpse of his palmed ball of foil - you also glimpse his humanity.  I hope Teller isn't really mute... I think he was talking during the post-show photo-op... and does that camcorder bit mean we heard him speak!?  Penn's a great actor if that was scripted!  I guess I have to conclude that it was a worthwhile show for its blend of comedy, illusion, and commentary.  \nI wonder if they implanted a subliminal message about getting dessert afterwards (okay, he said it out loud).  Too bad we didn't look at our ticket stub because there was a coupon for free dessert attached!  The Rio is missing out on a huge money maker by not directing the departing crowd towards in-house choices.
