And just when you thought we were done talking about Charlie Sheen ... The former 'Two and a Half Men' star was the talk of the show, for a minute anyway, on the latest episode of 'The Marriage Ref' (Sundays, 10PM on NBC).

Without actually speaking his name, The Ma-Sheen's ex-wife, Denise Richards, revealed a little about Sheen's controlling ways while comparing their marriage to the show's latest cross couple.

"I lived this," Richards told host Tom Papa after watching clips of a woman expressing frustration fueled by her husband, who was obsessed with placing obnoxious instructional signs all over their home. Richards recognized the sign issue as a "control thing," while making a not-so-strong attempt to mask the identity of whom she was really talking about.

"He probably could have used a sign or two," snapped 'Saturday Night Live' cast member Seth Meyers, who appeared as a guest referee with Richards and George Wallace.
