Family's reaction to Jake Guentzel's goal is great

How do you turn your family from mild-mannered observers into party animals?
If you're Pittsburgh Penguins rookie forward Jake Guentzel, you bury the first shot of your first NHL shift against the team that once drafted your dad.

After Jake's first career goal gave the Penguins a 1-0 lead over the Rangers Monday night, the camera cut to his celebrating family. Mom and dad were a combination of euphoric and stunned, but brother Ryan Guentzel was ready to party like it was 1999.
The closest comparable reaction to Ryan Guentzel's, in terms of energy level, was when Roberto Benigni won the

back in '99. Ryan took to Twitter to have a little fun at his own expense quickly after.

For good measure, Jake Guentzel scored another goal, popping in a rebound to give Pittsburgh a 2-0 lead in the first period.

Perhaps spent after the first goal, the family's second reaction, while still joyous, was much more subdued.
