A funny joke that my arabic dad told me :"the boy who wanted onion flavoured ice cream"

One day , The ice cream shop has a visitor , It is a little boy , The shop keeper says "Welcome , You came to the right place for your ice cream needs young man!" The little boy shouts while he is still at the door : "Do you guys have onion flavoured ice cream?" , The man is suprised and said: "no ,we don't sorry" the boy leaves The next day at the same time the boy comes in , The shop keeper out of habit says "Welcome" but he sees that it is the boy and silences him self thinking the boy is mad . The boy says :"Do you have onion flavoured ice cream?" The man says :"No , We dont".

That keeps going for 2 or 3 weeks until the man thought to himself:"You know , Why dont i make onion flavoured Ice cream for the little guy?" and he stood up all night to make it great . The boy comes the next day , "Welcome" says the shop keeper, The boy says the usual lines :"Do you have onion flavoured Ice cream?" the man excitingly says : "Yes we do" the boy then says : "Wow you guys must be retarded , Who would buy that shit"
