It began with Hall of Fame rocker Nils Lofgren offering a profane Twitter takedown of former blink-of-an-eye White House communications chief Anthony Scaramucci. The clapback from Scaramucci, widely known as the Mooch, was a hilarious self-own that “nobody knows who” Lofgren is.

The result? Twitter wags roared. David Crosby (Note to Scaramucci: he’s also a musician) slammed: “Nils is so much more of a human being than you, Mooch.”

Some on Twitter hoped Scaramucci wasn’t seriously hoping to replace Sarah Huckabee Sanders as the next White House press secretary because he’d probably have to brush up on his knowledge of key cultural references first. (Maybe not.)

The E Street Band guitarist kicked off the confrontation on Twitter Friday, lashing Scaramucci’s earlier interview on MSNBC when the Mooch insisted Sanders spoke “what she thought was the truth at the time she was saying certain things.”
