Faldage and Bean, I take your point about context. However, Bean's examples still make me wonder why people don't just say, "He walks the talk," or "He doesn't walk the talk." The extra talk and extra walk don't make a helluva lot of sense to me - seem extraneous, like saying "each and every" (which nevertheless has a rhythm to it - possibly why people use the ttt & wtw forms). ttt & wtw just sounds funny to my ear, is all.
