Man Repellant

I've never been what one might call "striking".  Yes, I had my Gremlin stage like most adolescents.  But now I would rate myself as a strong 7.  Not really a looker, but not a troll either.  So imagine my surprise this weekend while away at a conference when not one but two completely unknown men tried to chat me up.  I am happy to report that in unwanted situations such as these, merely uttering the statement "I am a (female) biochemistry professor" is sufficient to repel such vermin.
