Send this to 15 people or else you will get pregnant!

No, I haven't seen any as asinine as that yet, but I hate it when I get sent stupid crap like this on IM every day though...

"[5:34:55] tomorrow morning your crush will fall madly in love
with you. You guys will hook up, and your crush will
ask you out. Tomorrow will be the best day of your
life. However, if you don't send this to at least 10
people bye @ least 10:00 tonight you will have bad
luck in you love life for the rest of your life. This
is not a stupid one or a fake. Just copy and paste"

That is copied verbatim (though I so wanted to correct the grammar) from a message I received today. The scary thing is, I get all these from friends, most of them level-headed and smart. What do they hope to accomplish, besides the endless propagation of a few lines of poorly-written text? We may never know.
