Let's make this birthday one to remember.

66 years old (Born on April 23, 1959)

Happy Birthday to the ever-brilliant Dan Frischman! Whether it was acing equations as lovable nerd Arvid Engen on "Head of the Class" or navigating comedic chaos alongside Kenan & Kel as Chris Potter—the ultimate geek-next-door—you've kept us laughing and cheering through decades. You've turned being quirky into an art form, showing nerds everywhere that smart is indeed hilarious.

Here's wishing this new year brings you more success (and fewer wedgies), overflowing joy (without splashing orange soda all over your suit), and plenty of reasons to shout proudly: "Coolness factor be damned—I’m still a genius!" Cheers, Dan!
