It’s fan etiquette 101: Don’t take a foul ball (or a hockey puck) from a kid.

During Thursday night’s hockey game at the Consol Energy Center in Pittsburgh, Pennsylvania, one guy learned that the hard way.

In the second period of the Pittsburgh Penguins versus Buffalo Sabres game, a puck ricocheted into the Sabres' bench.

Coach Dan Bylsma, who spent several seasons behind the bench in Pittsburgh, scooped up the puck and pointed to a young fan sitting a few rows behind the bench.

Bylsma tossed the puck over the glass to the little boy, who was anxiously awaiting a cool souvenir.

Then the unthinkable happened.

An adult snatched the puck before the kid could catch it!

Maybe the guy had good intentions with the puck, but come on, it was clearly intended for the kid.

The crowd at Consol Energy Center booed for quite some time as the man refused to hand the puck over to the kid.

The whole time, the young fan stayed composed and handled himself like a true gentleman.

Bylsma later made things right and flipped the kid another puck.

Then the Penguins took matters into their own hands and got the boy a Sidney Crosby sweater.

Way to go, Pens!
