Grandpa... bought a rubber

Chrysler LeBaron Town & Country and kept it in his wallet, just in case a water landing went bad for Grandma.

True Story:

Grandma:  This car (rented LeBaron)  is nice enough, but i would never want to own one. Everyone else:  Huh? Why? Grandma:  Because it only comes with power windows. Everyone else:  Huh? What's wrong with that? Grandma:  What if you drove into a lake and they shorted out?  How could you escape? MythbustersWatch our show, old lady. Grandpa:  No, Grandma. Don't watch.
