Meanwhile, Homer suffers a back injury by a bull from the rodeo and sees a chiropractor, but does not follow his instructions. Later, Homer falls backward onto a malformed garbage can at home and discovers that it solved his back problems. He makes a business out of his discovery, which proves to be a successful method of solving problems with pain, causing the chiropractic business to decline. Eventually, two chiropractors disguised as investors trick Homer and destroy the garbage can at the Simpsons' home.
