Oh, and the world will end on May 20th 2011
I don't know if this is the same rumor or a different one, but nutcase Harold Camping, the founder of Family Radio (which actually has some decent programming), again says he has calculated the day of the Rapture, which is May 21st, 2011 (according to him). Thing is, this is at least his third or fourth such prediction. He's been asked what he'll do or say on May 22nd after it doesn't happen, but he says if you believe something, you don't entertain such thoughts.
Aside from that, I don't know if this is in the same category, but I once heard a driver telling another that when he gets a cold, he downs antibiotics. If you've kept up with the news, you're familiar with growing antibiotic resistance due to their overuse. But this guy has things mixed up; says that it's vitamins you shouldn't take. But he sounds very sure of himself, can't tell him otherwise.
