Happy Birthday, John McEnroe! Another year older, yet your legendary Wimbledon tantrums remain forever young. Who else could turn "You cannot be serious!" into a timeless catchphrase? Your fiery passion and unmatched talent on the court have given tennis fans unforgettable moments that still make us smile (and umpires cringe).From your epic battles at Wimbledon to your insightful commentary today, you've proven that age is just a number—though perhaps the racket tosses are fewer now. May this birthday bring you as much joy as winning seven Grand Slam singles titles did. Keep serving up laughs and aces!
