Buster Keaton stood stone-faced and unflinching as the front wall of a two-story house crashed down around him in Steamboat Bill, Jr. (1928). Harold Lloyd dangled from a clock face above a traffic-filled city street in Safety Last. Comedy stars of old Hollywood frequently put themselves in danger, risking serious injury just to get a laugh — a tradition continued, with more literal balls, in MTV’s Jackass (2000). Though Steve-O’s silent-film-star willingness to risk hurt and humiliation (see also: his six-week stint on Dancing with the Stars), nor even his degree from literal Clown College, guarantee he’s any good at stand-up comedy, he’s been honing his stage show since 2001, and his 2016 Showtime special delves into his struggles with sex addiction and his experiences in therapy, revealing a surprising amount of depth for someone with a full back tattoo of himself giving a double thumbs-up. You thought he was just going to hit himself in the nuts with the microphone, didn’t you?
