A traveling salesman visits a small town in the Midwest and sees a circus banner reading, Dont Miss the Amazing Goldstein!

Curious, he buys a ticket and sits through the usual circus acts: animals, clowns, contortionists, etc. Suddenly, trumpets blare and all eyes turn to the center ring. There in the middle of the ring is a table with three walnuts on it. In comes a little old Jewish man, five feet tall and barely able to walk to the table. He unzips his pants, whips out his long shlong, and proceeds to smash all three walnuts with three mighty swings! The crowd erupts in thunderous applause as the elderly Goldstein is carried off on the shoulders of the clowns.

Twenty years later the salesman visits the same little town and he sees a faded sign for the same circus and the same Dont Miss the Amazing Goldstein.

He cant believe the old guy is still alive much less still doing his act! So he buys a ticket and sits through various acts. Finally, the center ring is illuminated. This time, instead of walnuts, three coconuts are on the table. As before, old Goldstein takes forever to make it to the table. He unzips his fly and proceeds to smash the coconuts with three swings of his amazing shlong.

The crowd goes wild! The salesman requests a meeting with him after the show. In Goldsteins dressing room, the salesman tells him hes never seen anything like his act. But he wants to know why hes now smashing coconuts instead of the much easier walnuts.

Vell, says Goldstein, my eyes arent vhat they used to be!
