T-shirt wisdom

It occurred to me that there is a certain kind of philosophical wit or wisdom that is not serious enough to be expounded upon in a monograph but is too mind-expanding not to express. Let us call this kind of wit "T-shirt wisdom". I got the idea from an episode of Dirty Jobs with Mike Rowe, where he meets a duck and goose processor who was especially quotable.

I guess I'll start.

If you want to scratch your nose, you've got to find it first.

Song in my head: Seether, "Careless Whisper".

P.S. If you haven't already guessed, "nose" in the above t-shirt wisdom did not originally read "nose". ^_^
