To paraphrase Dirty Harry: A (geriatric) woman has got to know her limitations.

Hillary Clinton, a 68-year-old grandmother, was captured on the campaign trail awkwardly fist-bumping a fan.

While campaigning in North Liberty, Iowa Sunday, Clinton was greeting fans after a rally when someone stuck a fist out of the crowd. Seemingly pondering an attempt to shake the fist, Clinton instead opted to bump it while hanging her fist in the air for several moments.

“Heeeeyyyyy,” she said in Fonzie-esque style with a strange smile on her face.
