A woman had 3 girls. One day she decides to test her sons-in-law. She invites the first one for a stroll by the lakeshore, purposely falls in and pretends to be drowning. Without any hesitation, the son-in-law jumps in and saves her.

The next morning, he finds a brand new Toyota car in his driveway with this message on the windshield.

"Thank you!
Your mother-in-law who loves you!

A few days later, the lady does the same thing with the second son-in-law. He jumps in the water and saves her also. She offers him a new Honda car with the same message on the windshield.

Thank you!
Your mother-in-law who loves you!

A few days later, she does the same thing again with the third son-in-law. While she is drowning, the son-in-law looks at her without moving an inch and thinks: "Finaly! It's about time that this old witch dies!

The next morning, he receives a brand new Ferrari car with this message…

THANK YOU!
Your father-in-law.
