Happy Birthday, Merry Christmas. This is for people who are stuck with someone who was born on Christmas and can’t stop celebrating both at the same time.
My friend’s birthday is on Christmas and she kept saying 'Happy Birthday, Merry Christmas' at my house until I left.
My coworker was born on Christmas and kept texting me 'Happy Birthday, Merry Christmas' for an hour.
My dad was born on Christmas and he said 'Happy Birthday, Merry Christmas' to my mom while she was cooking.
