Men need periodic oil change 
and many serial killers, rapists, mass murderers look very
decent also
Thing is, I think quite a few of these men
are married with kids.
Which just brings me back to something I've discussed with an
Aussie guy friend - that maybe, we just aren't meant to be
monogamous afterall because no one person can fulfill all our needs
and it just makes us jaded as we all attempt to be happily faithful
when all the while, we meet other people who kinda tug at our
heartstrings and make us wonder, "What if... " 
Not that I'll actually accept an unfaithful man, nor a
polygamous marriage myself, but I mean, for the sake of discussion,
maybe, monogamy just isn't such a fantastic idea afterall...
