I like her. I like watching her because most of the standup they show on Comedy Central sucks. Basically, if it's on Comedy Central, you can assume the whole routine is "my wife is bossy and withholds sex" jokes and the occasional "I got drunk one night and..." joke. Ellen could be horrible, but honestly, I wouldn't know because she's a freakin' oasis from the other garbage they show.
I usually just have the tv on in the back ground during the day and her show comes on all the time. It was really annoying at first, but I'm starting to not mind it so much now. Some things that she does bug me, but at the same time, even though she has celebrity guests on the show, she gets the audience really involved and makes regualr people feel like they're something, too. Gotta give her credit for that.
