There's the old joke about the Dalai Lama going to a hotdog stand and saying, "Make me one with everything."
Then he pays with $5 bill, and asks for his change, to which the vendor replies, "Change comes from within."
Here's a reporter trying to tell a variation of that joke to the actual Dalai Lama. It falls completely flat, but still is pretty funny on a kind of meta level. That reporter is now trying to schedule a priest, a minister, and a rabbi for his next interview.
Millions saw the apple fall, but Newton asked why.
If you understand, say "understand". If you don't understand, say "don't understand". But if you understand and say "don't understand". How do I understand that you understand? Understand!
