Country singer Mel Tillis, who was a frequent guest on "The Glen Campbell Goodtime Hour," had a substantial stammer. But it didn't bother him when he sang. He used the stammer in comedy routines. Standard gag:   H-h-he would m-m-m-make s-some c-c-comment, to which Glen Campbell would respond huffily, "Well, that's easy for you to say. . . ."

Comedienne Geri Jewell has cerebral palsy and appeared in a number of television shows, and she also used it in her stand-up comedy routines. "I have pierced ears. I hadn't planned on it. I was trying to pluck my eyebrows. . . ."

And then, there's Josh Blue.

The wheelchair (polio) doesn't seem to inhibit Michael Flanders much. He just ignores it and goes ahead and does his thing.
