6679 - Long joke Sunday

The mother-in-law, comes home and finds her son-in-law furious and packing his suitcase.

"What happened?" she asked.

"What happened!? he said.

"I'll tell you what happened!"

"I sent an email to my wife saying that I was coming home from my trip today.

I got home and guess what I found?

My wife, yes, my Rachel, with a naked guy in our marital bed! 

This is the end of our marriage, I'm leaving!"

"Calm down!" says mother-in-law.

"There is something odd about this story.

Rachel would never do such a thing!

Wait a minute while I check what happened."

Moments later, mother-in-law comes back with a big smile. 

"You see, I said there must be a simple explanation!

Rachel didn't receive your Email."
