Watch: Who is Faster on a Zamboni? Crosby or Malkin?

Sid and Geno love to compete, especially against each other. This time, the future Hall-of-Famers climbed aboard Zamboni machines for a race across a parking lot.

GAME ON!

It's Crosby vs. Malkin in a zamboni race for the ages.

This has to be our best @keybank challenge yet. pic.twitter.com/EDYslOyO00
