It might have been Donald Trump's assurance that he has no size problem "down there" that prompted it. Or maybe it was the schoolyard-style fighting between Trump and Marco Rubio in Thursday night's Fox GOP debate.

Hillary Clinton posted a tweet that used humor to make a good point. "How many more of these do we have to sit through? Asking for a friend."

It is accompanied with a GIF of her suffering through a congressional hearing on Benghazi.
