A friend of mine who has been living here for a long time but still and continued to speak broken English.  He did not and still does not know the word, diarrhea.  One day, he was really having issues with that so he decided to go to the pharmacy to get something for it.
 
Pharmacist:  “How may I help you?”
Ping:  “E-k-s-cuse me.  I need medicine.  I shit too much with a lot of water.”
Pharmacist:  “Pardon me.  What did you do with a lot of water?”
Ping:  “I shit, you know, Poo Poo” he also added hand gestures to demonstrate the “action.”
Pharmacist:  “Do you mean you go to the bathroom too often because you drink lots of water?”
Ping:  “No, no.  Too much water in my shit.  No drinking.”
Pharmacist:  “Oh, I see.  Follow me.”
 
By the time he finished telling the story, I was in tears, on my knees on the floor with agonizing pain in my tummy.
