A McDonalds coffee mug with a joke in Dutch about fishing and a Float.
IMI promotions Utrecht-Brussels-Paris translated it says
"There are two men fishing. One asks the other can I get a float from you borrow you? "Yes says the other but why? Mine keeps going down. "
Sorry if my translation is off. I used google translate
I am not sure that this is really funny or not but I know there are McDonald's collectors that would like to have a foreign McDonalds coffee mug
