Here's looking at you, kid. Big Daddy's unique, humorous Playgirl greeting card line adds an extra bit of fantasy to every day or special occasions, depicting boyish men with eyes and smiles begging to dance the horizontal mambo. Whether the card says "They say 40 is the new 20" or "When you were his age, he was still in diapers" (among other themes), people most fond of sending cards (statistically, women) will have a reason to write you a thank-you note.$
