The mother-in-law arrives home from shopping to find her son-in-law, Paddy in a steaming rage and hurriedly packing his suitcase.
"What happened Paddy?" she asks anxiously.
"What happened? I'll tell you what happened! I sent an email to my wife telling her I was coming home today from my fishing trip. I get home ... and guess what I found? 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'm leaving forever!" ;
"Ah now, calm down, calm down Paddy!" says his mother-in-law.
"There is 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, there, I told you it must be a simple explanation. She never got your email!"
