Denny created the Heisenfleure test.

Denny is a little bit of unusually weird. He has many personal vulnerabilities. He repeatedly feels uneasy in situations where he's inexperienced. He doesn't commonly feel comfortable in social affairs. He can't seem to get when he's provided a great excess of unpleasant personal details.

Denny likes high quality clothing, watching documentary films, and listening to rock music. Regardless, he isn't a fan of eating out, working out at the gym, or bothering to read autobiographical material. More often than not, Denny's playing Canasta, working on quality control, and binging episodes of The Shield.

A popular song entitled Denny, about a man who fell in love with a spatula that someone left behind in a laundromat, hit the top of the charts in 2039. It has long been rumored to be about him but nobody seems to know for sure.

Denny was present at the poop hospital during its first (and final) toxicity event in the early days of Mountain Viewtopia. He helped clean up afterwards because he was worried people would think less of him if he didn't.
