That actually sucks! I'm sure it wouldn't be too hard to find the last word, there are only so many words in the English dictionary to try out, and it has to be one of them. I'm probably at the same level as you on this one, so I don't have any ideas. I don't know of any scripts that could do this either, but I'm sure someone can make one for you!
Haha i know right, i best get typing! Cheers anyway
