The San Jose Sharks were defeated soundly by the Los Angeles Kings Thursday night, but they're still holding down a 3-1 lead in their opening round Stanley Cup playoff series. Perhaps it's that comfortable cushion that allowed Sharks' players to keep it light Friday, despite the fresh memory of a Game 4 drubbing. 

Of course no one keeps it lighter than effusive Sharks rookie Tomas Hertl, who even took the time to pose for photographs wearing a Teenage Mutant Ninja Turtle mask:

The thing to remember here is that when Hertl sports "the mask" he's not just dressing up in a Teenage Mutant Ninja Turtle costume, he's quite literally becoming the character/t-shirt sensation known as Teenage Mutant Ninja Hertl. 

Smile on, sweet mutant.
