Michel: You owe me.
Lorelai: What? I do not.
Michel: Oh, yes, you do. Last November, when you were going out of town and nervous about boarding Paul Anka for the first time, you forced me, against my better judgment, to have Paul Anka over to my home for the day so he could acclimate to other dogs. Well, not only did he traumatize my poor chows, but somehow he managed to get into my closet, the door of which was firmly closed.
Lorelai: I know. I don't know how he does that.
Michel: ...and proceeded to poop in my Prada loafers.
Lorelai: Well, he knows good quality.
Michel: When I returned your foul creature and told you about what happened, you apologized profusely and then wrote an I.O.U. on several little Post-its, thinking it was all so clever.
Lorelai: Gosh, I don't remember that.
Michel: I thought as much.
