So, what’s the joke?
In any case, I assume it is in here:
"...This week the administration announced it was going to unleash financial hell on our enemies by cutting them off from every possible source of income. Then if that works in Canada, we might try it in Iran as well. The Canadians objected to this in that girishly adorable little petulant way they have. And so our president was forced to teach them a lesson by putting a 50% tariff on their major exports to our country like hockey sticks and boredom. The Canadians, who really are cute when they're mad, retaliated by continuing the negotiations in French so no one here could understand what they were saying.
Meanwhile, in Iran, Trump has declared that the Strait of Hormuz is now completely under our control and will be moved to upstate New York and renamed the Strait of Screw You Canada. The president says the Iranians are only days away from surrendering and admitting this whole Quran business was just a prank to get people to blow themselves up because they thought that would be funny. Trump says the end of the war would have been negotiated long ago, but we killed so many of their leaders that now the only Ayatollah left is a one-legged homosexual who's afraid if he steps down, the mullahs will throw him off a building before they find out about the whole fake Quran thing.
The Ayatollah has been so busy since he was anointed by Allah, that he feels like a one-legged man in a Gay Pride Parade blowing-up contest.
