Bruce Willis is a longtime Letterman vet, and whenever he stops by the show, weird stuff tends to happen. Such as tonight’s segment, in which the two men simultaneously ate a cob of corn attached to Willis’s face with some sort of self-fashioned corn harmonica. Although, believe it or not, this isn’t even the weirdest instance of Willis-Letterman food-related bromance: That distinction goes to the time that Letterman ate a molded ground beef toupee off Willis’s head. Seriously, these two.
