Life pro tip: Don’t fall asleep in a car when Dana White is a fellow occupant.

The UFC President Dana White had some fun with former UFC welterweight champion and current trainer Matt Serra, and he posted video proof (via Instagram).

A word of warning: White’s harsh wakeup call elicits some strong language – and a world-class mean-mug – from Serra.

While UFC Fight Night 70 took place in Hollywood, Fla., on Saturday, White was apparently focused on another project. Earlier this month, the UFC executive said he was developing a new reality series with Serra, who quit fighting in 2010 and officially retired in 2013, and longtime friend Nick “The Tooth” Gall. White said filming would begin this weekend.

White offered few details about the series but suggested it would be shopped to TV networks (and wouldn’t be carried by UFC Fight Pass, the UFC’s digital streaming service).

White, of course, is no stranger to travel-related pranks. In early 2014, former boxing champ Mike Tyson forced White to give us his seat on a private plane – and then took a marker to White’s forehead while he was sleeping:

Alright it's official no more flying with @miketyson !!!! #ufc #miketyson #sharpie #dontfallasleep
