Lately, I've seem plenty of good deals through Groupon and Living Social for standup comedy and it has been my experience that this is one of the cheapest forms of entertainment in Vegas. The American Casino Guide best coupon in my opinion is the 2 free tickets to the Riviera comedy and the 2 for 1 to Big Al's at the Orleans is good as well except for solo travelers.
Bill Maher is not so cheap, however. Still, if I get to Vegas sometime when he plays I'd like to see him live.
