I watched Ellen Degeneres' HBO stand up special a few months ago and was kinda surprised at how funny/clever she is.
It has to be Tina Fey. Or maybe Kristen Wigg I swear they should just rename SNL The Kristen Wigg show at this point. She's in every skit.
Definitely Jane Lynch and her delivery in Glee. I have no idea how she can keep a straight face saying half the shit that character is required to say.
Okay I thought we just meant people on tv shows. Top funny women are Ellen Degeneres, Jane Lynch, Lampanelli, Silverman, and thats it. Trudy from Reno 911! is pretty funny too.
