Wile E. Coyote and the Road Runner are fictional characters from the Looney Tunes and Merrie Melodies cartoon series. In the cartoons, the Coyote repeatedly tries to catch the Road Runner. However, the Road Runner runs very fast. That means the Coyote never gets the Road Runner.
Instead of his animal instincts, the Coyote uses complex traps to get his prey. They don't work, and often hurt the Coyote instead. Many of these traps are mail-ordered from companies named Acme.[1]
