Nike's "Just Do It" slogan was based on the last words of a convict before he was executed by firing squad:

The murderer was Gary Gilmore, who had grown up in Portland, Oregan – the city that is home to both Nike and Wieden+Kennedy. In 1976 Gilmore robbed and murdered two men in Utah and was executed by firing squad the following year (by some accounts Gilmore actually said "Let's do this" just before he was shot).
