Play a Pathfinder 1e Unchained Monk, pick up Breaking-Down Koan, flavour your koans as devastating puns, and you can spend ki points on puns.

You can also pick up the other koan powers, but I think Breaking-Down Koan fits best.

Text reproduced for the curious:

Breaking-Down Koan (Su): A monk with this ability can spend 1 ki point as a swift action to present a paradox, riddle, or complicated question to a creature within 30 feet. The creature must succeed at a Will save (DC = 10 + 1/2 the monk’s level + his Wisdom modifier) or be confused for 1 round. This is a mind-affecting, language-dependent effect. A monk must be at least 8th level before selecting this ki power.
