Our guide to stand-up, improv and variety shows happening this weekend and in the week ahead.

‘CHAOS THEORY’ at Caveat (Sept. 10, 7 p.m.). Imagine a TED Talk that turns into an interactive adventure. That’s essentially what happens in this show, hosted by Jessica Creane. Under the guise of Dr. Genevieve Saoch, Creane brings her theories on chaos to life by asking audience members to play along in a series of games that dare them to leave their comfort zone. This experience is enjoying a monthly run at Caveat through the end of 2019.

NEIL HAMBURGER at the Bell House (Sept. 7, 7:30 p.m.). With a horrible comb-over and frumpled tuxedo, and haphazardly clutching a drink or even two, Gregg Turkington has transformed himself into this ultimate anticomedian persona for more than two decades. Hamburger has toured internationally as an opening act for Tenacious D, and even starred in an independent movie, 2015’s “Entertainment,” imagining his alter ego’s life both on- and offstage. The act is a crude throwback, but it’s all in good, mean fun, taking aim at famous comedians and other celebrities.
