Puppet Up!

Puppet Up! is a show that was started "to demonstrate what happens when the perilous and provocative forms of traditional comedic improvisation are mixed with the art of puppetry." The show was originally titled Jim Henson's Puppet Improv, and also evolved into Stuffed & Unstrung.

The sketches in the live show are not pre-planned, and the shows contain all true improv. The puppeteers in the Henson improv troupe trained with Groundlings performer Patrick Bristow for nine months to perfect their improv skills prior to their first show; and monthly performer training classes continue to this day. Just like the Groundlings, the Henson Improv sketches are performed based on audience suggestions.

The show is strongly advertised for "adults only" and as "uncensored." First introduced in 2006, Puppet Up! was the Henson Company's first project under the Henson Alternative banner, a brand of productions with more mature themes and content than those traditionally associated with Henson Company.

The troupe performed monthly shows at the Avalon Hollywood until Stuffed & Unstrung began.
