Happy Birthday to everyone's favorite physicist-next-door, Johnny Galecki! May your birthday be filled with more laughter than Leonard Hofstadter at Comic-Con and less drama than David Healy navigating Roseanne's kitchen. You’ve made geeky look effortlessly cool—and sweater vests suspiciously fashionable!From awkward roommate moments on "The Big Bang Theory" to stealing our hearts as the lovable underdog in "Roseanne," your comedic timing has always been flawless. Wishing you another year of success that's bigger than Sheldon's ego, happier than Penny buying you dinner, and way less complicated—hopefully—than quantum physics. Here's celebrating Johnny: keep inspiring smiles worldwide!
