The dog food
We've been watching our DVD set, and there's been a large bag of Iams dog food leaning against the wall near the refrigerator, looking suspiciously like product placement.
Last night we watched S7E7 "The Thanksgiving Show," wherein they discover that Mabel is allergic to Murray's food. I'm guessing we've seen the last of the Iams bag. Well, either that, or Murray will start eating the Iams hypo-allergenic variety!
