Did you know what undiagnosed STD can cause mental disorders? Or which wild animals can be gay? Or anything about duck penises? Zoltan Illes, a former international biology teacher turned comedian, will answer all these questions and more in the critically acclaimed Nerdy and Dirty. Set up like a class you actually want to attend, Zoltan (real name) will conduct lessons that seamlessly intertwines his nomadic, globe-trotting life as a clueless American with educational facts you definitely weren't taught in school, presented by a teacher who says things he probably shouldn't.
