So, a guy walks into a bar, and he tells the bartender, "After this last drink, I'm going to the roof to kill myself." A guy sitting next to him says, "I wouldn't do that if I were you.", in which the man replies, "Oh yeah?" So, they both take their shots and go up to the roof. The guy says "You're not gonna die, watch this!" He jumps off the roof and comes back up. The man rubs his eyes and tells him to go it again. He comes down and comes back up. The man says "Cool, let me try!", and he jumps down only to kill himself. The guy goes back to the bar, and the bartender says "Superman, you're an asshole."
