Justin Williams is known as Mr. Game 7 because he's 7-1 with 14 points in the seventh game of a series in his career.

That said, Williams may have some company as Matt Cullen improved to 7-0 in Game 7s Thursday night after the Penguins' win.

Matt Cullen shall forever be known as Mr. Game 7. #7 is now 7-0. He also won 70% of his faceoffs. #LetsGoPens

After the game, Cullen's three sons joined him in the locker room to celebrate the victory that sent the Pens to the Stanley Cup final for the second straight season.

During the celebration, head coach Mike Sullivan told Cullen's kids about his dad's undefeated record in Game 7s, and one of his sons had the greatest reaction.

Sullivan said 8-0, but he made a mistake, and it happens.

Don't let the mistake distract you from the fact that Cullen's son just shrugged off the incredible feat.

@penguins @edward_soukup Cullen's kids shrugged it off like no big deal 😂😂#savage

Penguins fans are probably hoping their team can win the Cup in less than seven games, but at least they know if they do go to seven, they've got Cullen and his kids on their side.
