Oh No You Dent! Denture Tablets
From Homestar Runner Wiki
Oh No You Dent! Denture Tablets are the denture tablets The King of Town uses, claiming that they are his "after dinner mints". Strong Bad combined them with Mountain Dew to destroy the Tandy 400 in retirement. The package describes them as "disgusting old person tablets", and they come in packages of 100. The tablets are produced by Very Old Inc. The product's name is a play on the common phrase, "Oh, no you didn't!"
