Divided into sections according to how much you love him (or how much cash you have to drop on a Father's Day gift).
Level 1: Not Much Love/Not Much Money
World's Best Dad baseball cap. For a dad who's always been there for you, but damnit you just had to replace the brakes on your car and you don't have much cash.
Father's Day card. This should at the very least be included with all other presents on this list. But if times are tough/you just reconnected with your dad after he left your mom 16 years ago/you have a step-dad and he's kind of a jerk, the card might be the route for you. It says, "I care, but not much."
Note: If you really hate him, make sure it's written in Comic Sans.
What do dads like? Sports and being able to tell you how great they used to be at sports. Buy him a football and you'll get to see him in action. This is a great opportunity to embarrass a bad father, or to grow closer with a good one.
Level 2: I Love You/I Just Got Paid
It's not a super fancy set, but it's everything you need* to pack up the ol' station wagon and head out on an adventure with dad. Definitely something to buy if you want to spend more time together. Pair this with a weekend reservation at a nearby state park and you'll look like you actually put some effort into Father's Day.
Cost: $100 for the camping set, $30 for state park reservations
