Something about a host laughing during their own show always cracked me up. In any situation, whenever the funny guy breaks character and cracks a smile it's always great. Especially when it's a guy like Conan or Letterman. Norm MacDonald and Tracy Morgan used to get Letterman a bunch but other than that he was pretty much stone faced. Which is part of the reason why he was so great- because he was able to make the guest the joke without them knowing it. Anyway, I've said it before and I'll say it again, Conan O'Brien is the best late night host on television hands down. Have a great Friday.
