Robin Williams has been better known for his acting than his stand-up routines in the past few years, but that doesn’t mean he’s turned his back on the trade. In fact, he’s currently working on new material and has two sold-out Showbox shows to show for it. If you’re one of those curious to find out what he’s up to and haven’t gotten tix yet, you get one more try: The Showbox has added a third show for Thursday, May 24th. Tickets are $45.00 and go on sale Wednesday, May 23, through Ticketmaster.

Williams is one of those comics I can take or leave–he has his moments when he’s very, very funny but then he has his moments when he’s very, very not. I wouldn’t turn down the chance to see him if it didn’t require effort on my part but I wouldn’t put the effort into going to see him. I find him mostly “okay”, I guess–I don’t think he sucks, I’m just not impressed. I am impressed, however, to learn that his proceeds from the show are going to Challenged Athletes Operation Rebound [site], an organization that provides post-rehabilitation support and mentorship to American soldiers and veterans who suffered traumatic injuries in Afghanistan and/or Iraq that resulted in a permanent physical disability. It’s a great organization that can use all the help it gets (so true of so many good organizations), so I applaud Williams for giving them a hand.
