Lol, that's just too funny.
I once fired an employee for similar reasons.
She called in sick, and said that she wouldn't be able to come to work for 3 weeks, because of medical reasons.
After looking up her profile on Orkut (much more spread here in Brazil than Facebook), I noticed that she was partying everyday with friends, and telling everybody how she fooled her employees.
Needless to say that I fired her on spot when I read those messages.
