Jimmy Stewart was a legendary actor and military officer. He's considered one of the most popular and honored stars in film history.
Stewart also had a wonderful dog named Beau, who fell terminally ill while Stewart was away filming. Stewart's wife, Gloria, wanted to put Beau down. The vet called Stewart to ask permission, but he wouldn't reply. "‘Keep him alive and I'll be there," is all he said. Stewart got permission to go home for a few days and spend time with Beau before putting him down.
"After [Beau] died there were a lot of nights when I was certain that I could feel him get into bed beside me and I would reach out and pat his head," Stewart recalled. "The feeling was so real that I wrote a poem about it and how much it hurt to realize that he wasn’t going to be there any more."
Jimmy Stewart then appeared on Johnny Carson, and recited a poem he wrote for his beloved pup. Everyone thought it was a joke at first, but they were wrong.
