Bill Murray can even make falling off a chair while drunk seem charming and charismatic! The 64-year-old actor appeared on Tuesday night's penultimate episode of Late Night With David Letterman where he hilariously jumped out of a cake and chugged vodka with the 68-year-old late night host. But all that drinking may have been a little to much for Murray to handle because his appearance on MSNBC's The Last Word later that night didn't go so smoothly.
