I spent a whole afternoon trying to remember a dad joke about a doorknob, figured it out while I was cutting carpet in a house near Spokane. The punchline only works if you say it with the right pause, and I kept messing it up for my wife. She finally laughed after I wrote it on a scrap of vinyl and taped it to the bathroom mirror. It was a dumb play on 'turn the other cheek' and 'check the other knob', not my best work. Took me 45 minutes total, but the payoff was a genuine snort-laugh. You ever spend way too long perfecting a joke that barely lands?
