I'm Not Laughing, Mr. Morgan

Tracy Morgan is supposed to be a big, funny comedian, but I don't get this latest joke -- the one where he drinks alcohol, then drives his car around the neighborhood and gets pulled over. Not to mention he's already tried this joke twice before and it wasn't funny then so why would it be funny now? I guess it's like my joke about me juggling animals with my pants around my wife's ankles: you had to be there.
