Translating is difficult and sometimes while the intent is good and the idea behind the sign can still be understood they end up being terribly wrong. I am not judging anyone because I know translations, particularly from Germanic to Asian languages, can be very difficult... This doesn't mean I can't find them funny.
Check out these gems:
To anyone who can't read Thai this would catch their eye. However, in Thai it actually says "The Future" also as it is the name of a business that is quite well-known and very popular. It is kind of funny that you need to make a U-Turn to get to it though - thereby making it necessary to go "back to the future."
Oh you only missed one letter. It probably wont make much of a difference. Another funny point about this advert is that in Thai it says "100% grape" but there are pictures of other fruits on the box and if you look at the contents it is definitely not 100% grape juice. In fact, it contains mostly apple juice.
The punishment seems excessive for taking some sugar cane. PS, i didn't even approach the plants. This was taken yesterday during my waterfall trek.
I will admit that I did not take the last picture but I remember seeing them all over the place a couple of years ago. This was the source of quite a lot of embarrassment because they were distributed on a relatively large scale and normally errors would be ignored. However, despite the country's reputation as a sexy sexy place, the official stance towards this sort of thing is that they are really conservative publicly.
That's it for now. You really don't have to look very far to find something that almost makes sense on a sign over here and it can be a lot of fun. Just as a disclaimer I am not trying to hurt anyone's feelings or trying to say that these people are dumb - translation is very hard and even though I speak and read Thai I am quite certain if I were to make a sign in Thai that if it made sense at all, it would still be funny to Thai people because I would almost certainly do at least a couple of things wrong.
