Donut in one hand, bad idea in the other. D'oh!
Safety inspector at the Springfield Nuclear Power Plant, a job he is spectacularly unqualified for and mostly sleeps through. Lazy, easily distracted by food, and confident about things he has not thought through at all. Says "D'oh!" when it goes wrong, which it does, and "Woohoo!" when it does not. Under all of it, he would do absolutely anything for his family.
