A sarcastic birthday card for an Oklahoma State football fan. Background in OSU orange and black colors. A cartoon birthday cake that is burnt and lopsided. On top of the cake sits a football wearing a little âmulletâ wig. Text at the top of the image says: âHappy Birthday, Cowboy!â Text at the bottom of the image says: âCongrats â another year older. Unlike Gundy, at least youâve accomplished something with your time.â The style should be humorous, cartoonish, and bold like an e-card. See more
