Even at age 92, Dick Van Dyke has a pretty spry Twitter game.

On Sunday, the actor responded perfectly to a lame joke British TV personality Piers Morgan made about his name.

“Imagine being called Dick Van Dyke in this PC-crazed era?” Morgan began in his tweet. It got lamer.

Imagine being called Dick Van Dyke in this PC-crazed era?

Poor guy.

Good thing that Van Dyke’s “Diagnosis Murder” doctor, Mark Sloan, was on call to respond in a surgically precise takedown. No words necessary.

Van Dyke, who starred in “Mary Poppins” and will soon appear in “Mary Poppins Returns,” needed no accompaniment from a magical nanny to handle this one.
