Drew Carey is involved in a new hidden-camera show CBS is developing.

The project, with a working title of ‘WTF!’ (standing for Wow That’s Funny!), is currently in development with a pilot episode shot recently involving pranks performed in public.

The Whose Line Is It Anyway? host is collaborating with producer Tom Forman on the project which is described as “well-intentioned”. One example of the type of prank pulled is with the group transforming a late-night truck stop into a five-star restaurant for the benefit of long-haul truckers.

The show will adopt a similar style of light-hearted fun as CBS’s previous weekend hit Undercover Boss.
