My wife is about 18 months older than me.
Much hilarity has been had with that info.
Of course... she doesn't find it so funny...
I'm 7 years older than GC ... we have a great time with it -- Much to his ex-'s chagrin ... She was soooo pissed when she found out she couldn't tell people he left her for a younger woman ... That's his ex- ... ever the victim.
(For those of you who are now wondering -- he didn't leave her. She kicked him out so she could marry a doctor. Twelve years later she is still single. )
