This duck walks into a convenience store and asks the clerk, "Do you have any grapes?"

The clerk says no, and the duck leaves. The next day, the duck returns and asks, "Do you have any grapes?" The clerk again says no, and the duck leaves.

The day after that, the duck walks in the store again and asks "Do you have any grapes?" The clerk screams at the duck, "You've come in here the past two days and asked if we had any grapes. I told you no every time that we don't have any grapes!

I swear if you come back in here again, and ask for grapes, I'll nail your webbed feet to the floor!!" The duck left, and returned the next day. This time he asked, "Do you have any nails?"

The clerk replied, "No," and the duck said, "Good! Got any grapes?"

Michael Idvorsky Pupin

Born 4 Oct 1858; died 12 Mar 1935 at age 76. Serbian-American physicist who devised a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire. His parents were illiterate, but they encouraged his education. Pupin became an instructor in mathematical physics (1890) at Columbia University, New York City. In 1986, he discovered that atoms struck by X rays emit secondary X-ray radiation. He also invented a means for taking short-exposure X-ray photographs. The Bell Telephone Company, in 1901, acquired the patent for his invention for long-distance telephony. Pupin won a Pulitzer Prize (1924) for his autobiographical work, From Immigrant to Inventor (1923).
