Happy Birthday, Matthew Waterhouse! From navigating the TARDIS as Adric—solving equations faster than most of us can find our keys—to charming audiences in "To Serve Them All My Days," you've certainly mastered time travel and timeless performances. Who else could make mathematics look heroic while dodging Daleks?Here's wishing you a birthday filled with fewer Cybermen invasions and more cake-filled celebrations. May your adventures continue to inspire laughter, nostalgia, and perhaps another trip through space-time (just remember: always double-check coordinates!). Cheers to many more years of success—and may your birthdays never be exterminated by boredom!
