Krusty's primary source of income is the almost neverending amount of merchandise he puts his name and face to. Unfortunately, Krusty's love of money means he endorses absolutely anything suggested to him regardless of quality, and brands it with his seal of approval without even looking at it before doing so. As a result, the Krusty brand has become a dumping ground for products from inept companies that know a celebrity endorsement is their only hope for selling their product, and sometimes even malicious companies wishing to harm or exploit children. It has gotten to the stage where he can't endorse any more merchandise because there is nothing left that he hasn't already endorsed.
