A Trump joke; did I read this on DU?

Today’s Trump joke: It was Meat Identification Day in Mrs. Smith’s third-grade class.

She handed out the first sample. “Everyone try this and tell me what you think it is.”
Johnny stood up. “Mrs. Smith, that tastes like beef.” Beef it was.

Then comes the second sample.
Mary said, “I think that’s turkey, Mrs. Smith.” It was turkey.

Then the third sample was presented. No one knew what it was.
Mrs. Smith said, “It’s something that your mommy sometimes calls your daddy.”

Tiffany Trump started screaming, “Spit it out. It’s asshole.”
