Her excuse . .
Mother-in-law came home from the shops to find her son-in-law fuming and raging and packing his bags, and she asked him what was wrong.
"I'll tell you what happened", he replied. "I sent an email to me wife telling her I was coming home today from my fishing trip.
I get home... and guess what I found: Yes, your daughter, my wife Jean, naked with Joe Murphy in our marital bed!
This is unforgivable, the end of our marriage. I’m done. I am leaving forever!"
"Ah now, calm down, calm down Paddy!" says his mother-in-law. "There is I something very odd going on here.
Jean would never do such a thing! There must be a simple explanation. I'll go speak to her immediately and find out what happened."
Moments later, the mother-in-law comes back with a big smile... "Paddy, I told you there must be a simple explanation
. . .. she never got your email!”
