Has Matt?
From Homestar Runner Wiki
Has Matt? is the HAZMAT "team" called to hose down Strong Bad after he made a slit in his couch that emanated a stench of "biblical proportions" in couch patch.
The team seems to consist entirely of The Poopsmith, wearing a blue hazmat suit labelled "Has Matt?" He wields a garden hose with which to hose down any persons exposed to dangerous chemicals and/or stenches.
