What was the most consecutive penalties a team has ever killed?

So, the Caps have killed 11 straight short handed situations (and scored a goal on the last one), and it got me thinking, what was the most in a row a team has killed? Now, obviously, it's hard to measure, since some of those PKs might have been very short ones at the end of a 4-on-4, or something like that, but given the man advantage gives the offense an edge, I'm interested in how long, both in time and total PKs, that was the most short handed opportunities without giving up a goal.

BQ- In the spirit of Mardi Gras coming to an end down here a few days ago, what is your favorite PARTY holiday of the year, how do you like spending it, and if you could go to any holiday celebration in the world, which would you choose and why?
