You're familiar with dad jokes, aren't you? They're usually puns, or literal answers to questions, or dance moves.
This is not a dad joke. It's a joke made by a dad, sure, but the punchline is you. Welcome to the most brutal graduation card you will ever see:
The card was uploaded to Reddit by user Lootman, and it reads (because apparently if dads have a massive sense of humour, the pay off is tiny writing): "You have now accomplished the absolute minimum standard of our society. Here's some money."
Which, y'know, yay money. We guess.
