Irv Benson is one of the last survivors of one of the most incredible eras in show business — the days of vaudeville. He made numerous appearances of “The Tonight Show with Johnny Carson,” played comedic roles in theater productions and now he’s featured in a multi-award winning documentary called “The Last First Comic.”

The 100-year-old tells us what it feels like to be 100 and whether he ever aspired to be a centenarian.

He also gives us a fascinating look back on his career, which began at the age of 13 when he was a dancer. Even though he never reached the kind of fame Johnny Carson and Red Skelton achieved, he explains why he was so thrilled to be a part of this unique era of entertainment.

And listen to his priceless reaction to us bringing up one of his most famous bits, Sidney Spritzer, a heckler who harassed Milton Berle.
