In a loss for all parties involved—fans, media, players, the league, the country, our collective sanity—New England Patriots quarterback Tom Brady was re-suspended Monday by a United States appeals court for his supposed role in Deflategate, an alleged football deflating scheme the Patriots used during the AFC Championship Game in January 2015.

Whatever. This is stupid. But of course, with news this big, everyone needs to weigh in. Enter: Red Sox slugger David Ortiz, who used this metaphor to describe Brady’s fight against the NFL:

“When you fight eggs with a rock, the eggs never win,” Ortiz said, via WEEI.

Wait, what? Sure, this makes sense from a technical standpoint. Like, if you fought a car with eggs, the car would win. But why exactly are we fighting with eggs in the first place?

Someone please explain the origins of this metaphor.
