Let's make this birthday one to remember.

68 years old (Born on August 14, 1957)

Happy Birthday, Peter Costello! As Australia's longest-serving Treasurer (1996-2007), you balanced budgets longer than most of us balance diets. Your legendary fiscal discipline made accountants swoon and politicians sweat—quite the achievement!

And let's not forget your fearless fight against corruption as chairman of the World Bank's anti-corruption effort. You tackled shady dealings with such gusto that even corrupt officials considered early retirement.

Here's wishing you a birthday filled with laughter, cake—and absolutely no budget cuts on fun today! May your celebrations be surplus-filled and deficit-free; after all these years crunching numbers, you've certainly earned it. Cheers to many more prosperous birthdays ahead!
