Dick Van Dyke, 92, puts Piers Morgan in his place on Twitter

The world spins, the sun rises, and Piers Morgan makes stupid jokes on Twitter. This time, though, it was actually a little fun for the rest of us -- thanks to 92-year-old film and TV icon Dick Van Dyke.

On Saturday, Morgan -- who is on the wrong side of history 90 percent of the time -- thought it would be a good idea to crack a joke about Van Dyke's name. "Imagine being called Dick Van Dyke in the PC-crazed era?" Morgan tweeted. "Poor guy. He'll have to change his name to Richard Van Non-Binary-Gender-Fluid."

(To be fair, this joke is doing a lot of work: It's condescending, misogynistic, and homophobic.)

Here's how Van Dyke responded. No words, just the perfect screenshot from Diagnosis: Murder.

And perhaps that's the best way to deal with the Piers Morgans of the world: saying nothing, staring incredulously for a moment, then moving on.
