American comedian and actor Robin Williams (1951-2014) said:
 
“Ah yes, divorce, from that Latin word meaning to rip out a man’s genitals through his wallet.”
 
It’s uncertain when Williams first said it, but the one-liner has been cited in print since at least 1997.

“CBS This Morning” co-host Gayle King noted Williams’ own definition of divorce, saying, “I thought this was hilarious: (you said) divorce is derived from the Latin meaning ‘to rip a man’s genitals out of his wallet’.”
 
Williams replied, “That was an old, old joke. ‘Through his wallet,’ but thank you. Old, old joke, but thank you for bringing that back. Come kick me in the heart.”
