What are some Chinese characters that an English speaker might find humorous if explained to them?

How about this character?

It looks like a face that is sad, tired, shocked, or embarrassed. In fact, it is used on chats and forums online to show those exact emotions.

The character is pronounced jiǒng (ㄐㄩㄥˇ) and originally means “window,” but it also adopted the meaning of “bright.”

I think it’s pretty funny, don’t you?
