Simon has a pun for you to solve. It’s a problem involving logic and language that makes more sense in Dutch but is understandable in English, too. Here are the two questions of the problem:
Wat was was voor dat was was was? (What was was before was was was?)
Wat is is voor dat is is is? (What is is before is is is?)
Simon explains the answers in the video. He did not invent the problems himself but the explanations are his own.
