There’s a classic Seinfeld episode in which Elaine dances at a work party, employing her thumbs and little kicks in a routine Kramer dubbed a “full body dry heave.”

Something similar was on display in South Carolina Thursday night.

Hillary Clinton danced. In front of cameras.

She kicked things off with a little head bob, feeling the grooves of Charlie Wilson. After warming up, she broke out a reverse hand wave, as if brushing aside Bernie Sanders’ attempt to steal the coronation from her, along with the unwashed masses sharing the same ballroom with her.

“Go Hillary! Go Hillary” the audience chanted.

She flashed a classic Clinton thumbs-up.

It’s not the first time Hillary’s been caught on camera with her odd moves. Back in August, she was seen using similar hand gyrations at a Martha’s Vineyard birthday party.

Bill was seen clapping off beat, and Hillary — poor Hillary — doing some sort of jazz hands routine. Bill adds some half-hearted fist twirls, standing closer to another woman as Hillary shimmied and swayed.

It’s something you might see at a senior center, not a hip party with rockin’ music on Martha’s Vineyard.

WARNING: This view cannot be unseen.

It was a party for former Clinton adviser Vernon Jordan’s 80th birthday.
