Father's Day Cards

Why is it that most father's day cards tend to have something to do with work?  There's a tie... or a briefcase... or a man wearing a tie with a briefcase.  If you're lucky, you might find one with something to do with grilling.  Is that what Dads do?  Work and grill?  I've tried to find a few cards that have fun messages or have to do with some other interest your father might have so that you don't have to remind him that on the day after father's day, he has to go back to work.  Have you picked up a great father's day card yet?  If so, where is it from?  I'd love to know.
