The short version: Joe Rogan is shilling for Robert F. Kennedy Jr.'s vaccine conspiracy theories, and demanded this weekend that Dr. Peter Hotez, vaccine expert, appear on his wacky podcast to debate Kennedy.

Now, Hotez has been on the infotainment show several times, and is happy to have a discussion. But he refused to agree to a circus of a debate with Bobby Kennedy Jr., whose own family knows he's a wack job.

So after Hotez said no, Rogan went to work riling up his flying monkeys on Twitter, to the point where a Qnut showed up at Hotez's home and confronted the scientist.

And because this is Twitter, the usual suspects came out of the woodwork to defend Rogan and Kennedy. I don't need to tell you Kennedy is being backed for the Democratic presidential nomination by Steve Bannon and his minions, right?

Oh, and Elmo Musk got involved, too.
