I find both white and black comedians funny.

Some of the funniest comedians you will hear are white. Thier delivery is just different. Meanwhile Black comedians have mastered the delivery part but the jokes can be redundant. Reason why is a lot of black comedians dont research their materials like some white comedians. This black comedian was talking once...cant recall who.. anyway he said he doesnt get how some comedians can run out of material or be redundant and start biting others material. He said he gets 90% of his material from the newspaper. All you need to do to survive in the business is read.
I wanna say it was Cedric but might have been someone else like BruceBruce or DC Curry.

Some of my favorite comedians are white. Lewis Black, Seinfeld Carlin. They are some of the few white comedians that not only have great material but also great delivery.
Hellen is very underrated BTW
