The classical Latin for “Good” is Bonus and for “Bad” is Malus. So that could be the basis for a pun.
Q) What would you call a bunch of extra Malayalees?
A) Bonus Mallus. 😛
This would be funny only if a person knew that Malus is the classical Latin for “Bad” and that Bonus is also used to refer to stuff that you got for free or that you got as an extra . And if so, are those romans saying Mallus sunt malus?
Also, the Pun is technically called Paranomasia. That actually sounds like some sort of disease. I think my entire batch suffers from Paranomasia.
