VIDEO: Remembering the Time Someone Hit a Fellow Fan With a Pizza Slice at a Red Sox Game for National Pizza Day

Losing can take a toll on even the most upbeat fan, and sometimes those fans find all new creative ways to lash out and express their frustration. Especially when they're a couple beers deep at a baseball game. On National Pizza Day, let's hop in the WayBack Machine and take a look at arguably the only case of pizza-based fan warfare in sports history. During a Boston Red Sox home game against the Los Angeles Angels, one fan was so fed up with his team's performance that he threw a slice of pizza at a fan who interfered with a foul ball.

To be fair, he may have been aiming at Angels outfielder Garrett Anderson, but either way his slice ended up draped over the shoulder of the unsuspecting fan, who had already been doused by his own beverage.

Imagine paying nine dollars for a subpar ballpark pizza slice and deciding to use it as a weapon.

The fan who threw the pizza was asked to leave the ballpark, and probably hasn't been asked back, but the memories he gave us still persist.

If the Red Sox make good on their mandate to trade Mookie Betts for a return that clearly doesn't look good given the type of player Betts is, we might see a few more pizza slices angrily hurled from the arms of angry Boston fans.

Among other things.
