I'd received that joke a couple times via email. The stereotype has been stand-up comic fodder for years. I didn't see it as any more racial than an NBA-African-American joke. As it was submitted as a joke, I took it at face value. Whether I chuckle or not is up to me.
FWIW: some of the best tech/customer support I've ever received has come from the stereotypical, heavily accented English speaking personnel. The last one even wished me a, not "Happy Holidays", but a "Merry Christmas." That beat my local Post Office. LOL
