Let's make this birthday one to remember.

77 years old (Born on August 13, 1948)

Happy Birthday to the brilliant Merrill Markoe! From crafting unforgettable laughs as head writer for David Letterman's original show, to penning witty episodes of "Sex and the City" and "Moonlighting," your comedic genius has kept us chuckling through decades. Your Emmy-winning humor remains timeless—much like our confusion over shoulder pads in '80s fashion.

May this birthday bring you more joy than a perfectly timed punchline, more applause than a Letterman monologue, and fewer awkward moments than Carrie Bradshaw's dating life. Here's hoping your day is filled with laughter worthy of your legendary wit—and cake that's fresher than late-night jokes!
