You gotta let 'em know you're out there. It's the playoffs.

Patrick Warburton, the actor who played over-zealous New Jersey Devils fan David Puddy on the iconic sitcom "Seinfeld," was in the building for Game 4 of the Eastern Conference First Round series against the Tampa Bay Lightning on Wednesday.

Warburton went to the game in full character, sporting the famous Puddy face-paint that had his TV girlfriend, Elaine (played by Julia-Louis Dreyfus), questioning her choice of boyfriend during the 1995 episode of the series appropriately titled "The Face Painter."

"This is always a lot of fun to be here. I've been a Devils fan since they adopted me," Warburton told NHL.com. "The Devils are my team and it is always great to be back here."

Earlier this season, a handful of Devils players wore T-shirts with Puddy's painted face on them. Warburton tweeted his approval then and was fully into it on Wednesday night, posting a selfie to his Instagram account before the game.

The actor even went as far as to paint a giant, red letter "D" on his chest, just as he did at the end of the episode. He pulled his jersey off and screamed "Don't mess with the Devils! We're the Devils! We can beat anybody! THE DEVILS!" into the mic to fire up the Prudential Center crowd.

Because, hey, you gotta support the team.
