Looking for a night of no-strings-attached adult fun? Then go check out the raunchy improv puppeteers of Henson Alternative as SHN and SF Sketchfest present Stuffed and Unstrung, whose 10-show limited engagement starts tonight. This lolzfest is created and produced by Brian Henson, who also stages irreverent conversations between salmon and one-eyed aliens that tip-toe between genius and lunacy in the manner that only interspecial and intergalactic dialogues can. Throughout the show, you’ll learn about life, love, and a new alphabet song that starts with “F” and ends with “K” -- but your wallet won’t be as f$%^ed, as tickets are only $30 - $65. If you’re dying to learn more about the courageously comical humans behind (and inside) these furry creatures, Stuffed and Unstrung is hosting two free post-show behind-the-scenes talks on Aug 18th and 25th, where you can seek career advice from those who get paid to make lewd jokes via a diaper-wearing dog. There are only 10 shows, so get your tix now, because unless you frequent the bowels of the internet classifieds, you’ve never had filthy-puppet fun like this.
