A young person is a child, grows up, grows old, and then becomes like a child again. So, too, with your sense of humour: while you might be too cool for a knock-knock or a two-line pun in your teens or early twenties, something happens when you turn 30+ (or sooner if you have kids!). Those jokes become funny again, and so much so, that you feel it's your duty to share them with the world (or your kid's friends).
Bored Panda scoured the Internet for the finest two-liners and came up with this list. Which one is the most cringe-worthy? Or maybe you have a few two-liner jokes of your own?
