Nope no joke, appears to be a heart defect poor mitch he was one of the best comedians I've ever seen. His just for laughs performance was amazing.

"I bought a seven dollar pen because I always lose pens and I got sick of not caring"

"I never joined the army because at ease was never that easy to me. Seemed rather uptight still. I don't relax by parting my legs slightly and putting my hands behind my back. That does not equal ease. At ease was not being in the military. I am at ease, bro, because I am not in the military"

"I think Bigfoot is blurry, that's the problem. There's a large out-of-focus monster roaming the countryside."

"I don't have a girlfriend. But I do know a woman who'd be mad at me for saying that"

RIP Mitch
