Saturday Morning Cartoons

"Just sign this form, and the money will be yours." - C.M. Burns

The above is a perfect example of proper plot exposition and minor character usage.  I would submit this in direct contrast to, say, Rev. Lovejoy not being holy for a while, Skinner and Comic Book Guy chasing an ancient riddle and especially magical tomato sauce.  

Homer needs $5,000, Burns gives it to him because Homer doesn't understand the word "usury", and the story moves along.  There are no words wasted and no more time taken than necessary.  The five grand is never mentioned again because it doesn't need to be.  Everyone acted in character; Homer made a poor financial decision and Burns tightened his stranglehold on Homer's tiny life.  It's hilarious, it fits, and it ends quickly.  

I love this show.
