Here's a funny sign my wife spotted. The sign reads "YangWei, ZhaoXie" which if read sounds exactly like the sound for the words "Impotence, Premature Ejaculation" in Mandarin. It actually advertises for a Chinese doctor, we assume for these conditions.
What's remarkable, besides this sign being out in the open on a major thoroughfare, is that the characters used are totally wrong. We assume that it was done to throw kids of the scent.
However, kids are pretty smart these days. I give them more credit than perhaps the sign creators have. My guess is that kids and adults alike will get a chuckle out of this sign.
Of course, it is entirely possible that the creators of the sign knew this would happen all along and did it for effect. They make a futile attempt at hiding the meaning, knowing all the while the marketing job is done and they have covered their asses in the eyes of prudish parents.
That's Taiwanese ingenuity for you!
