This is actually a trick question. If the first three words are 'The boys down' then the last three words are also 'The boys down', It's a phrase, it only consists of three words so therefore the first three words are also the last three words.
This was a question asked on a Ugandan Radio station as part of their 'Brain Game'. It was/is a quiz where they increase the prize money every hour until someone guesses correctly.
This particular question stumped people for months, but I am not sure of the actual amount that the winner got, it must have been a lot though!
In England, we have a station called 'Heart' who often run a competition called 'Who's on Heart' which also stumps everyone for a long time. The way it works is that they have three celebrities who each say a word - either 'who's', 'on' or 'heart'.
As you can imagine, that isn't easy and to be perfectly honest, I can't even tell if they are male or female sometimes!
