With BOGO coupons,  Comedy Stop at the Tropicana only costs $10 per person, which includes 1 drink each.

Three comedians keep the crowd laughing the entire time.  Definitely profanity and stuff, so don't go to this if you'll be offended by that kind of thing. 

The Comedy Stop is a good option if you'd like to do something different but don't have a lot of cash.
