My dad always told me to never put off until tomorrow what you can do today.

This joke gets its chuckle from a delightful twist of irony and a dash of absurd wordplay. The setup presents a classic piece of fatherly wisdom, a maxim that most of us have heard and perhaps even tried to live by: the idea of tackling tasks promptly rather than delaying them. This advice is all about productivity and forward momentum.

However, the punchline brilliantly flips this well-intentioned guidance on its head. Instead of inspiring diligent action, the speaker applies the "don't put off" rule to the very act of procrastination itself. This creates a humorous paradox, suggesting a person who is so committed to their habit of delaying things that they can't even delay the act of delaying. It's a clever subversion of a familiar saying, playing on our own struggles with getting things done and finding humor in the most convoluted ways to avoid actual work.
