From How to talk like Jacques Derrida (Guideline 4):
"Pun like crazy: The thought (which when taught, becomes taut, tight, tense, stretched to breaking, which is to say ever looser as it becomes tightened) is illuminated by the pun, which has been called the lowest form of wit (whereby the bun may be termed the lowest form of wheat), to wit, a pun is more like a pin, which bursts the taut (taught) surface of the meaning, freeing it to explode/ implode in all directions at once."
