It’s the breakfast of champions.

One Philadelphia Eagles fan’s celebration of the team’s first Super Bowl victory turned downright nasty — as he ate from a pile of horse dung in the street as revelers cheered him on, new video shows.

The clip, posted on Twitter, shows the man, wearing an Eagles jersey, kneeling down on the street — and making sure his scarf doesn’t touch the pile of poop.

Then he takes a mouthful of manure, much to the crowd’s delight, the 40-second video posted by user Bryan Murphy shows.

The sickening moment was one of many disturbing incidents in the aftermath of the Eagles’ 41-33 Super Bowl LII victory on Sunday, the first in the franchise’s history.

Fans set fires, pushed over cars, leaped off awnings and climbed light poles, even though they’d been greased up.

Two Eagles fans were arrested in separate incidents for punching horses around the team’s two home playoff games.
