Mother in Law

A mother with three daughters one day decided that it was time to put her sons in law to the test ...
She invited the first one for a walk along the lake, she fell in the water and pretended to be drowning!

Without hesitation her son in law jumped into the water and saved her.

The next morning there was a car in his driveway with the message......
Thank you,
your mother in law
A couple of days later she “did” the same to her second son in law....

He too saved her and the next day he found a car in his driveway........
Thank you,
Your mother in law
Then it was the turn of the third son in law!!
He did not lift a finger and let the bitch drown!

The next day he too found a car in his driveway with the message.....
Thanks..
Your father in law!
