Crispin Hellion Glover on the David Letterman show

On July 28, 1987, Glover appeared on Late Night with David Letterman[3] to promote his new movie River's Edge and his album. Dressed as his character from the film Rubin and Ed, he wore a long wig and platform shoes. His bizarre appearance was exceeded only by his strange behavior, which was thought by some to have been influenced by drugs, while others presume it was an Andy Kaufman-style stunt. After a failed attempt to challenge Letterman to an arm-wrestling match, Glover delivered an impromptu karate kick just inches from Letterman's face while shouting, "I'm strong... I can kick!". A noticeably irked Dave abruptly ended the segment and cut to commercial. Glover has later commented, on The Adam Carolla Show and Tom Green Live among others, that he neither denies nor admits any of the rumors surrounding the incident.
