This is no joke. This is actually Donald Trump's first TV ad. In a mere 30 seconds it manages to be amazingly offensive and stupid.
“That’s why he’s calling for a temporary shutdown of Muslims entering the United States, until we can figure out what’s going on. He’ll quickly cut the head off ISIS and take their oil. And he’ll stop illegal immigration by building a wall on our southern border that Mexico will pay for.”
What? We already know "what's going on," there is no ISIS head to cut off (and anyway, remember how much killing Osama bin Laden has eliminated all our problems!), whatever oil they might have doesn't actually belong to us, and Mexico is not going to pay for a wall. The main result of trying to do such things would be to alienate a lot of people (at home and abroad) unnecessarily, look foolish, and damage U.S.-Latin American relations.
