Petrie: SHE tore the rug!
Ducky: You need to stop hanging around ambitious British with high self-esteems.
(That was actually inspired by a scene in Three Musketeers...1973. D'Artanian, played by Michael York (hense the "ambitious British with high self-esteems, since A LOT of his characters are ambitious) got into a room full of people and tore the rug, attempting to literally pull it out from under their feet so he could escape. As he leaves, some person quietly says "He tore our rug" and does nothing about it.)
