A couple of links for you:

http://www.snopes.com/humor/business/wordperf.htm

Actually, all of http://www.snopes.com/

This is a comprehensive site which tracks urban
legends, and gives their variants, first
appearance, and possible origins.  Before you
repeat one of these time-worn untruths, take a
moment to check Snopes and save yourself from
looking silly.

I didn't respond earlier, because anyone can be
fooled by an urban legend.  But sheesh, two in one
day was just too much to bear.
