Donald Trump is walking out of the White House and heading toward his limo when an assassin steps forward and aims a gun.
A secret service agent, new on the job, shouts, “Mickey Mouse!”
This startles the would-be assassin, and he is captured.
Later, the secret service agent’s supervisor takes him aside and asks,
“What in the hell made you shout Mickey Mouse?”
(Wait for it....)

Blushing, the agent replies, “I got nervous. I meant to shout, “Donald duck!”
