A Mother-in law wanted to check with her son in laws about their love for her. She took one son in law to a lake and accidentally fell in the water. The son in law saved her from drowning. Next day the son in law found a Honda with a card attached to it from the mother in law. After a week she did the same with the second son in law with the same result, and he too got a Honda. Next week she repeated the scene with the third son in law but he did not save her and she drowned. The following day the third son in law saw a Mercedes car near his house given to him by his father in law.
