However, something about Paul McCullough's life was not so easy. And to this day, nobody knows exactly what it was.

Bobby Clark and Paul McCullough teamed in 1905. They were very funny. Their short films from the early 30's are still very rewarding to watch. Clark was a Broadway comic with a style close to Groucho Marx...he wore painted-on eyeglasses, had a funny walk, waggled a cigar and delivered wisecracks and puns.

Partner McCullough was an amiable walrus of a sidekick, both baffled and delighted by his partner's zany ways.

One stage sketch, now a cliche but fresh at the time, had Bobby the Lion Tamer confused between McCullough in a fake skin -- and a real lion. "That's great, you're sure fooling the audience," he'd shout to the real lion. "What a performance. You even smell like a lion!" Ultimately, he had to race around the stage trying to get away from the vicious beast. "That's the real lion in there with you!" he's told. His curtain line: "This is a hell of a time to tell me!"

The team headlined on Broadway through the 20's and then made a series of two-reelers for RKO. They continued with their stage work as well.

McCullough gradually found himself battling depression, serious enough to require treatment in a Massachusetts sanitarium.

In March of 1936, McCullough went into a barber shop for a shave. After it was over, he suddenly grabbed the razor and flayed at his neck and wrists. He died in the hospital two days later.

A shaken Clark said, "I think it was just something Paul couldn't help. Something that had been with him all the time and he didn't even know it."
