You never know where he’s gonna show up, and that’s part of the fun. But that doesn’t stop him from randomly singing mid-set just to make fun of something. He’s not a singer, but he’ll throw in a dumb little jingle or sound effect if the joke calls for it.
If you’ve ever seen clips of his set and thought "damn, this guy’s fast," you haven’t seen anything till you’re in the room. These shows aren’t for the casual "haha" type. You don’t want to be stuck way in the back with people who don’t get the joke. Laughing so hard you’re wheezing next to some dude who drove five hours just to hear Mark talk about sandwiches and social anxiety. Grab those tickets early or get left crying on TikTok.
