think this falls into the 'how do you tell your dad his (male) business partner is a great lay'?
a childhood friend of mine was once at a rest area, ran into a guy who needing plowing 'bad'...so he did of course, in passing they exchanged names (his was an odd one) he realized it was his dads business partner (married with kids) of 30 years who he had not seen in a long while...whew.
