A Joke to Start the Week - "Half a Head of Lettuce"

It's another Monday and time for another Joke to Start the Week. Today Mickey Greenblatt is back with another good one.

Marshal (Mickey) Greenblatt received degrees from Columbia (BA and BS in Flight Sciences), a DC from Von Karman Institute (1963) and his PhD from Princeton in Aerospace Sciences. He worked as a researcher for NASA and the Naval Research Laboratory. 

With four other scientists, he founded Fusion Systems Corporation, which invented microwave-powered UV lamps for drying coatings. He founded and served on the boards of technology companies and is active in volunteer work. He served on the executive committee of the Jewish Council for the Aging of Greater Washington for many years.

Mickey also loves Jewish jokes and sent us this one to share with you. Here's the setup: The customer in the grocery store said to the clerk "I want to buy a half a head of lettuce." And then...

Enjoy!
