I know about something "witty" you can say if your friend (boy, that's what I call bad luck ! ) catches with his wife and it is : TAAA-DAAAAAA!!! HAHAHAHAHA... "Don't kid me, Mom, I know they're my feet." -- 3 year old son, when his mother told him his shoes were on the wrong feet... ooowwww

Tell me with whom you walk, I say unto whom thou art ...

The wit is out when the wine is in.

There's no fool like an old fool All that glitters is not gold

I'll try, but it's not funny (I don't remember who wrote it): The people that ignore History will (sadly) repeat it.
