Let's make this birthday one to remember.

64 years old (Born on October 28, 1960)

Happy Birthday, Mark Derwin! From navigating the hilarious chaos of parenthood in "The Secret Life Of The American Teenager," you've shown us that even fictional dads can have real-life charm. Your ability to deliver lines with perfect comedic timing has made every scene memorable—proving once again you're Hollywood's go-to guy for relatable fatherly wisdom (and occasional eye-rolls).

Here's wishing you another year filled with laughter, success, and fewer teenage dramas off-screen than on. May your birthday be as timelessly entertaining as your performances—and may cake calories remain forever secretive too! Cheers to more unforgettable moments ahead; keep shining bright!
