Thank you.

Something along these lines:
When Santa has burnt out at work, it starts thawing.

To burn out means to work yourself into exhaustion
To burn off has no such meaning. It means to remove something/get rid of something by or as of by burning. (like: I managed to burn off a lot of fat and now I look slim)
