It could be funny.
It could be really funny, but she has to overdo her sexist, racist humor to the point where it's overkill.
Is that her best material? I'm no prude, saint or pervert, but she is short on the jokes and big on the insults.
Her excuse is it's not racist if she pokes jokes at everybody...well it's not funny either.
There is an entire world full of stupid happenings and events that can be funny aside from just people's nationalities or skin color or sexual orientation.
10 minutes is far more than enough of this humor...an hour or so is by far too much.
Is the President or Vice President not doing retarded stuff any longer? Is George Bush all of a sudden a smart, generous, friendly person whit a heart of gold? Is there no events of traffic problems or confusion of sorts that can trigger some comment about daily life? Do I need to hear every 3 minutes about the size of you boyfriend's dick? Or how often you get laid or how a gay man is a fag? It's no longer funny when it's boring...and it gets boring quite easily.
Comedy is not easy to do and her show is not easy to watch unless you are truly a hillbilly with little sense and respect for anybody else.
