Have you heard about the guy who invented the knock-knock joke? He won the No-bell prize! But the real joke is that he tried to tell his invention to a door, but it just couldn't walk through it! So he ended up knocking on wood instead, hoping for a better response. But guess what? The wood replied with a knock-knock joke of its own! The guy was so surprised, he couldn't believe it – he just saw the furniture making jokes! But then he realized he was hallucinating and actually just talking to a talking table. It offered him a seat and they both had a good laugh about it. And that, my friends, is how knock-knock jokes became a furniture trend!
