Because we're in America, there are now several products on the market that enable you to stuff your stuff with more stuff. These contraptions incite a series of emotions that manifest in different stages.
Stage 1: One feels embarrassed, thinking this is American gluttony at its peak.
Stage 2: One becomes comfortable with the gluttony as one's imagination conjures up all kinds of creative stuff: mac and cheese-stuffed burgers; stuffing-stuffed turkey burgers; veggie-stuffed veggie burgers.
Stage 3: One thinks of non-food items one might place inside the burgers as a surprise for a most-favorite or least favorite BBQ guest: respectively, a toy soldier or a rubber mouse.
Stage 4: One realizes one absolutely needs this item, and when trying to purchase the item online, is surprised to learn that, at $12, the model from Williams Sonoma is less expensive than the stuffer from the aptly named company StufZ. Good stuff.
