Just about every day in the summertime, thousands of people join their voices together to sing a song which includes the name of a snack food. What song, what food?

During the seventh-inning stretch of nearly every professional baseball game, fans rise to their feet for a tradition that dates back over a century. The familiar tune they sing is "Take Me Out to the Ball Game," which has become the unofficial anthem of the sport. The lyrics famously call for classic ballpark concessions, specifically requesting "some peanuts and Cracker Jack," forever linking the molasses-coated popcorn and peanut snack to America's pastime.

What makes the song's legacy even more remarkable is its origin. Lyricist Jack Norworth and composer Albert Von Tilzer penned the tune in 1908, but shockingly, neither man had ever attended a professional baseball game at the time. Norworth was reportedly inspired by a simple sign on a New York City subway that read "Baseball Today — Polo Grounds." Despite their inexperience with the sport, their song perfectly captured the spirit of a day at the park and became so popular that it permanently cemented Cracker Jack's place as the definitive ballpark snack, creating one of the most enduring product placements in history.
