A protester who may have an incurable case of Trump Derangement Syndrome shouted at a animatronic lookalike of the president in front of a room full of children at the Happiest Place on Earth.

The ugly meltdown occurred in the Hall of Presidents at Disney World on Wednesday.

“I protested @realDonaldTrump at the #hallofpresidents cuz I’ll never get this close in real life probs,” Jay Malsky tweeted on December 27, adding the hashtag “#lockhimup.”

Malsky’s Twitter profile image shows him holding a purple dildo and advertises his “solo show” in New York City, titled, “Jay Malsky Slept With My Boyfriend.”

Malsky recorded himself watching the introductions of the presidents of the last half of the 20th Century to the president.

After George Washington introduced Trump, the current president recited the Oath of Office, only for Malsky to begin shouting “Lock him up!”

“Quiet!” another attendee responded.

Malsky chanted for over 40 seconds as others in the crowd drew tired of his tantrum.

“Shut up!” another one yelled.

Trump’s speech was halted as the crowd grew angrier.

“Please remain seated,” a staff member said over the sound system.

“Thanks, asshole,” someone could be heard telling Malsky as began chanting again.

The animatronic Trump was met with derision when it was unveiled shortly before Christmas.

Some said the face resembled Hillary Clinton’s.
