Well, now there's a new contender and it's stranger than the rest. Stove Top, Kraft's stuffing brand, has come out with Thanksgiving Dinner Pants.
Watch this and weep:
Alas, you won't be able to stuff yourself into these fugly $19.98 stretchy-waisted fat pants because they have already sold out. Wah wah.
Side note: I'm reminded of Betabrand's Gluttony Pants from a few years back.
