Why are Pirates called Pirates?
Because they Aarrrrrgh!
I do two or three pirate jokes that revolve around the Aaarrgh. Favorite animal Aardvark. Favorite state Arkansas..... Like this joke and then I ask my favorite one. The kids should think it's easy (but it's not).
(Me) What is a pirates favorite letter in the alphabet?
(all students)- Aaarrgh!
(Me) You'd think Aargh! But it actually be the "C".
Higher level students obviously. I have had some of my students (and other teachers) pissing themselves.
