In the second episode of “All-Around Losing,” Harry attempts to follow in the footsteps of Louis CK and other schmucks-turned-idols by trying to become a stand-up comic. He starts at the very, very bottom, subjecting himself to NYC’s brutal open-mic night scene, and quickly discovers that 1) making people laugh is nightmarishly difficult and 2) he is no good at it. It’s funny to watch him fail, but not ha-ha funny.
