OK. It hardly qualifies as a joke. More of a quip. As to funny or not, I'd have to hear the delivery. Knowing her, it probably was not funny. Comic timing is a natural trait, and she was not so blessed.
But, ahem, wtf is wrong with what she said? I assume the intended humorous idea of this remark is that Ghandi, a great and important man, arose from mundane origins, but those origins are transferred in the quip from his reality to ours. I guess Humoroligists have a technical term for what I'm trying to describe.
But, oh no! Just so happens that lots of Indians (S. Asian variety) do that in this country. Big deal. PC run amuk. She's a schmuck for apologizing, but then politics is a nutty world.
My biggest question is will fauxnews.com include this event in their regular round-up of PC abuses.
