William Shatner sings 'F*** You' on 'Lopez Tonight'

Has Cee-Lo Green launched a cheeky celebrity trend?

William Shatner takes on the musician's proanity-laced "F*** You" on Wednesday's (Oct. 3) "Lopez Tonight."

He adds his signature phrasing and perfomance skills, but doesn't skimp on the cursing. The censoring bleep is in full force, as it is on his CBS sitcom "$#*! My Dad Says," on which he plays the foul-mouthed curmudgeon Ed Goodson.
