Mavericks coach Rick Carlisle has a celebrity doppleganger, and he's finally willing to admit it.

It's been a long-running joke that Carlisle is basically the spitting image of comedian Jim Carrey, and with this year's Halloween costume Carlisle leaned into the joke by wearing a shirt reading "JIM CARREY DRESSED AS RICK CARLISLE." It's like Halloween Inception.

To be honest, Carlisle looks kind of freaky and maybe a little bit more like Wierd Al Yankovic that Carrey in this photo, but you can't blame a guy for trying.

Carlisle is currently in talks with the Mavs to sign a five-year contract extension with the team, according to ESPN.

Carlisle's costume joins a slew of other sports celebs who've been stepping out in full get-ups, including Lakers guard Nick Young, Alex Ovechkin's wife Nastya Shubskaya, and WWE Diva Paige.
