The NHL season came to a close on Sunday night and it was the Pittsburgh Penguins that had the honor of being the NHL's last team standing...again.

With a 2-0 win over Nashville in Game 6, the Penguins clinched the Stanley Cup Final and became the league's first repeat champions since the 1997-1998 Detroit Red Wings.

The Stanley Cup is often called the most difficult trophy to win in sports because of the long, grueling journey it takes to raise it.

With that in mind, the Cup celebration is always a treat (unless you're a fan of the team on the losing end) and a special moment for the group of guys who worked so hard to get there.

Here are some of the best photos capturing the Penguins' emotional celebration on Sunday night, from the ice to the locker room.
