This is a drift, but I just recall a humerous incident I had.

A few weeks ago I visited a Chinese take out place. Since they cater to chinese students, the menu on the wall was in both English and Chinese. I was kinda bored waiting, and decided to add a bit of humour to the day. So, pointing to a chinese character, I said to the clerk, there is a spelling mistake here. I expected her to "get' the humour, as it would somewhat be unlikely I would know how to read Chinese.

She looked it over closely and carefully, then called out the kitchen staff. They all looked the character over, discussed it in Chinese at length. I detected from their body language that they did not know if there was a mistake or not.

She then turned to me and said, "Sir, we will have it fixed by tomorrow" I thanked her, not wishing to indicate it was a joke, after putting them through such an ordeal.
