It should be a running joke that Matt never acclimates to smoking pot and every time is like the first time. So fast forward a few months, the lightbulb in their ceiling goes out and they have to replace it, and later that night after they've lit up (or maybe pot brownies, I bet Matt hates smoke because of his heightened senses and besides, brownies) Matt fishes the old lightbulb out of the trashcan and cradles it to his chest and says it'll be all ok little guy and refuses to part with it for the rest of the night.
