Let's make this birthday one to remember.

72 years old (Born on September 17, 1953)

Happy Birthday, James "Bonecrusher" Smith! Another year older and still packing a punch—though rumor has it your candles tap out before you even swing. With an impressive 44-17-1 record and the WBA Heavyweight Championship under your belt, you've certainly knocked life into submission.

From crushing bones in the ring to gracefully handling retirement (and birthday cake), you're truly timeless. May this year's celebration be as legendary as that unforgettable first-round knockout against Tim Witherspoon back in '86—and may no one dare challenge you for the last slice of cake today! Keep swinging strong, champ; age doesn't stand a chance!
