CSI Season 14 – Cheers’ John Ratzenberger to Guest Star

Cliff Clavin is going inside the yellow tape!

EW has learned that John Ratzenberger — who played the lovable mailman on Cheers — will reunite with his former co-star Ted Danson in a fall episode of CSI on CBS.

Ratzenberger will play a jaded, burned out club owner who’s been in the business for over 30 years, and he’s dazed when his business — and human lives — go up in smoke. And yep, he’ll get to play opposite Sammy Malone — er, we mean D.B. Russell (Danson).

The episode will air in October. CSI returns on Sept. 25.
