Ball&Chain is an improv duo.
 Press BlurbTheir press blurb, taken from a 2014 application to perform at The Hideout Theatre:
She's a hip gal from modern day Austin. He's a fast-talking guy from 20s-era Chicago. They're married. This out-of-time couple delivers an improv comedy show exploring the nature of all kinds of relationships that happen even if they don't make sense. It's just so crazy it works - that's the magic of Ball & Chain (real-life married couple Ruby Willmann and Troy A. Miller).
 "What's Your Deal?"Their answer to the "What's Your Deal?" question on a 2013 application to perform at The Hideout Theatre:
Our deal is that we're really a couple - yeah, not a novelty in improv - but we're taking our real-life age difference to the extreme, by playing our onstage personas as a couple consisting of individuals from two different time periods, spanning nearly 85 years.
