Well, beards were considered a very valuable thing among the dwarves, so it's much more likely that he would have said such a thing in one of the hobbit movies, possibly as a compliment or polite remark (i.e. "may your beard grow ever longer"). I cannot think of any specific examples though, unfortunately.
I do know that Gimli at one point says, "Not the beard!" although I doubt that would fit what you're looking for.
