It’s a well known fact that when men become dads, their jokes become terrible. Call it a quirk of biology. Nobody knows this better than Raylin Pellatt, a student from Michigan State University whose dad, Joe, just made her 21st birthday memorable with his adorably awful dad joke. “Happy 21st Birthday to my beautiful daughter (left) Raylin!” he wrote in a Facebook post recently, alongside a picture of his daughter on the beach. What’s so funny about that, you ask? Scroll down to see for yourself. Raylin shared his post on Twitter and it’s since gone viral with almost 600k likes and over 185k shares.
