Matthew Perry went off script

In the episode where Joey was dating a stalker who thought he was his ‘Days of Our Lives’ character Dr. Drake Remoray, Monica and Rachel throw water in his face.

Matthew Perry - who played Chandler Bing on the sitcom - also wanted to get in on the action so he threw a third drink of water at LeBlanc.

The look of surprise on Joey’s face is real as the goof wasn’t written in the script.
