The homeless man wandered onto center stage just as the spotlight went on. He shaded his old eyes against the brightness and looked outward into the dark theater. It was probably some kind of mistake.
“Oh, so now it’s my turn to talk, eh?”
There was no response.
“Well, if you’re expecting something funny to come out of my mouth, good luck with that. More than half of what I say that makes people laugh is the result of depression, ill health, and just plain ignorant stupidity. And the other half of it is not meant to be funny, but is because I don’t always understand what I am saying.”
There was an embarrassed chuckle somewhere in the darkness.
“I mean, you can’t expect too much from me. I’m a bum. I have no money. I have no job. Not having any work to be bothered with is kinda good. But the other thing kinda sucks.
And all the great comedians that used to stand on this stage and try to save the world through humor are dead now. It’s true. Robin Williams died recently. George Carlin, Bill Hicks, Richard Pryor, and Bill Cosby are all long gone.”
There was some nervous laughter in the theater.
“Oh, I know, Cosby only thinks he’s dead. But he kinda killed the character delivering the wisdom in the form of observational comedy, didn’t he.”
“But most of them old boys tried to come up here and tell you the truth. And the truth was so absolutely unexpectedly wacky and way out of bounds that you just had to laugh. And the more wicked the humor, the more you just laughed. You didn’t do anything about the problems they talked about. But you sure did laugh.”
“It seems like the more they told you the truth and the more you just laughed about it, the more old and bitter they got. Sardonic? You know that word? Not sardines, fools, but sardonic. Bitterly humorous and sadly funny. Seems like a lot of them old boys got more and more bitter, more and more depressed up to the end. More and more sardonic.”
“I mean, Carlin was calling you stupid right to your face at the end. And you just laughed it off.”
The theater had grown eerily silent.
“But it ain’t all bad, is it? I mean, at least you all can still laugh. Only smart people get the jokes. The ones Carlin moaned about were laughing because everybody else was laughing. Those weren’t the ones we were talking to. There’s still life out there somewhere. Maybe intelligent life. Maybe aliens ain’t located any intelligent life on Earth yet, but they’re still trying, ain’t they?”
“You shoulda listened more carefully to what they were saying. Life and love and laughter were bound up in their words.”
“So I guess what I’m really saying is… just because I happened to get a rare chance to say it to you all… learn to listen better. The voices are quiet now. But the words are still there. And laughing at them is still a good thing. But remember, you need to hear them too.”
The theater suddenly filled with the roar of a standing ovation. The old man bowed. And this was ironic because… the theater had always been empty. No one at all was there now.
