Premise: The East–West Shrine Game is an annual postseason college football all-star game played each January since 1925. The game is sponsored by the fraternal group Shriners International, and the net proceeds are earmarked to some of the Shrine's charitable works, most notably the Shriners Hospitals for Children. The game's slogan is "Strong Legs Run That Weak Legs May Walk".
Hypothesis: The East-West Shrine Game has been played every year since 1925.
