After years of fatherhood, dads tend to lose a bit of their, um, modesty. If Dad would rather sport a pair of ill-fitting tighty-whiteys than turn up the air conditioner, then this big, funny Father's Day card will be a great fit. Make sure you show Dad how much you appreciate his openness with a huge, hilarious Father's Day card. Don't be bashful about how much Dad means to you. Give him this large, laughable card. And in extreme cases, maybe a robe.
