Little's talents are showcased at the Riviera Hotel in Las Vegas.
"I was there 40 years ago, and I remember when I left, they said, 'Rich, we really like you. We want you back,' and so here I am," Little said.
He lives in Las Vegas with his wife and his one-eyed cat, but he also shares his home with his show-biz history, including those figures he so famously imitates.
It's all in the name of comedy.
Now 72 years old, Little also tours in a one-man play he wrote on the life of Jimmy Stewart, but that's not all he's written. He also wrote a book he's trying to get published called "Little By Little: People I Have Known and Been."
"So every chapter that I talk about somebody, I have a sketch of the person I'm talking about," he said.
Little is also the sketch artist, and he's figured out how to make a difference selling limited edition works of his art.
"I sell them with my memorabilia after a show's over. I sell my DVDs and my old TV show and some of my sketches, and then we give all the money to the families of the troops," he said.
Little has done a couple of USO tours and has tremendous respect and admiration for the troops.
Little performs at the Riviera Hotel five nights a week though June 12. For more information on his show, visit http://www.rivierahotel.com/.
