I just got home from the Improv in Homestead, PA and tonight’s act Jon Lajoie (pronounced Lajwah) performed a very entertaining set of stand-up infused with a couple of his popular songs. Lajoie, who plays the character Taco on FX’s TV series The League, earned his fame online with YouTube hits like “Show Me Your Genitals,” a parody of sexist rap songs, and “Everyday Normal Guy,” a rap song for middle class white men. Lajoie started his set with the list of rules for a stand-up comedian, but I’ve learned that the audience also has an unspoken set of its own.
