“Why didn’t the two fours want any lunch?”/“Because they already eight.”

A riddle on the homophones “ate” and “eight” is:
   
Q: Why didn’t the two fours want any lunch?
A: Because they already eight.
 
Four plus four equals eight—and this sounds like “ate.” The joke has been cited in print since at least 2008.
