For every head of the household, there is an ass of the household. We're going to assume you're probably the ass. If so, then these funny Father's Day cards are the perfect way to show your appreciation, and maybe even your newly found self-awareness, for everything your dad has had to endure over the years. Namely you, and your smart (whiney, unappreciative, annoying) mouth. So, this Father's Day give him something that won't make him cringe – a card given in silence.
