Rob Gronkowski, look what you’ve created.

As the Red Sox paraded through downtown Boston on duck boats Wednesday to celebrate their 2018 World Series championship, they were greeted by thousands of cheering fans — and scores of quickly oncoming beer cans.

Whether they were expecting them or not.

Of course, many Red Sox players were happy to accept the free beverages and showed off some impressive hands in the process.

Despite the revelry, public drinking remained illegal in the city Wednesday. Boston Police Commissioner William Gross said Monday that alcohol would “not be tolerated.” Those rules did not appear to apply to those atop the duck boats, including Chris Sale, who demonstrated that he isn’t just an ace at pitching, and Rick Porcello.

However, like in baseball, there are also a number of unwritten rules when it comes to flinging beers to the Word Series winners.

First, make sure your intended receiver is paying attention — especially when he’s the likely American League MVP. Not everyone feels as obligated to party as Gronk. Boston police even arrested a 19-year-old for throwing a can of beer at one of the duck boats and hitting a man onboard.

Another rule: no warm beers.

Dustin Pedroia just caught a beer then threw it down and yelled back that it was warm. Then caught a nip and spiked it, too. COME ON! DON'T GIVE WORLD CHAMPS WARM BEER, PEOPLE! #LaserShow #SoxOn7 #DoDamage pic.twitter.com/iy7CNyXFkN — ɐpoqoʌs ʎɐɾ (@jaysvoboda) October 31, 2018

Also, please don’t throw open beers, either.

Lastly — and likely most importantly — if you’re going to throw a beer, accuracy is important — as exemplified by the numerous, errantly thrown cans that either hit or overshot the passing duck boats.

The World Series trophy on Mookie Betts’s duck boat reportedly “took a direct hit” from a thrown beer, bending a few of its golden flags. Red Sox spokeswoman Zineb Curren told Boston.com that the trophy suffered “minimal damage” that should be “easily repaired.”

The Boston Globe also reported Wednesday that a 20-year-old bystander, Niamh Delaney, may need stitches after getting hit with an overthrown can on Tremont Street.

“It was coming at like 15 miles an hour, that thing nailed me,” Delaney told the Globe.


It’s dangerous to be the champs.
