The Chinese Cook
A freightship had a Chinese cook named Wang. The other crew members were always playing practical jokes on him, - rather rough jokes, like putting grease in his sleeping bag, or worse.
Wang took it all camly, always smiling, always polite, always minding his job. Finally, one day they decided that enough was enough; after all Wang was a nice guy, and he never hurt anybody, so everyone wowed never to bother him again.
Two hands went down to the pantry to break the news:
"Wang," they said, " we have all been a little rough on you, we know that. But you must understand that we meant no harm, we all like you a lot, and now everyone has promised never to play another joke on you."
Wang smiled happily and said:
"Then also Wang promise, never again piss in soup!"
