Barry, who has written humor columns for three decades, including 22 years at the Herald, says he's holding out the possibility of a return.
But for now, he says, "I want to stop before I join the horde of people who think I used to be funnier. And I want to work on some other stuff."
Barry says he will write occasional pieces, weighing in "from time to time if something really important happens, such as a cow exploding in a boat toilet."
In the column, Barry thanks his editors and readers.
"You've given me the most wonderful career an English major could hope to have," he writes. "I am very grateful. And I'm not making that up."
