You've probably heard about Donald Trump's claim that his Democratic rival got "a big fat se onhot in the ass" before delivering a nearly perfect performance on a recently televised town hall. Or his more recent demand that Joe Biden get a "drug test" before their debate on Tuesday night. Having spent months lowering expectations for Biden, the Trumps are now busily defaming him as a junkie.

But that particular slur backfired spectacularly over the weekend when the Trump campaign posted a bizarre video of Don Jr. -- seemingly in a condition that called for rehab services. As his father might put it, "many people are saying" that the presidential spud looked and sounded like someone abusing a controlled substance. (His slurred message was disturbed too, something about an "army of able-bodied men and women" to intimidate voters).

It's both funny and sad to watch Don Jr. decompensate on Twitter. (More funny, though.)

Click and judge his condition for yourself.
