I just happened to turn on Sirius in my car a little while ago and they were talking about the fake phone call to Peter Jennings during the OJ chase. Howard starts doing an impression of the fake caller with a 1920's over the top Southern Negro accent. Billy West jumps in out of nowhere to do a spot on Al Michaels impression. Robin can't let Billy have the spot light so she tries doing Al Michaels. At one point she says a joke that cracks herself up but nobody else. Therefore, she repeats the exact same joke 10 seconds later thinking they must not have heard her. I remember this happening a lot back then. Billy would be doing a Pat Cooper impression and Robin would constantly chime in trying to be Pat Cooper only entertaining herself. Common sense tells you when you aren't the funniest in the room you should let the professionals run the show. Her 34 ego and narcissism can't stop for one second. There has to be a name for this condition of forced/nervous laughter where she is constantly cracking herself up and no one else.
