[JamesM]

Son, a woman is a lot like a... [looks around] a refrigerator! They're about six feet tall, 300 pounds. They make ice and, um... [spots his can of Duff] Oh, wait a minute. Actually, a woman is more like a beer. They smell good, they look good and you'd step over your own mother just to get one! [downs the beer] But you can't stop at one. You wanna drink another woman!

“If you don’t like your job, you don’t quit. You just come in every day and do it real half-arsed. That’s the American way!” – Homer

Not from The Simpsons, but from Futurama:
A stray dog gets into the cryogenic freezing plant. The boss gets tired of chasing it around the factory floor and says "oh, freeze the goddamn thing". A junior employee says "Sir! You can't freeze all your problems!" And the boss says "I think you're forgetting the company motto" and points to a sign on the wall which says:
"You Can Freeze All Your Problems"
