My friend knows this riddle/joke which she learnt on mumsnet, but will not tell me the answer and despite months of me trying to work it out i still have no idea about it and she simply will not tell me. I know she learnt about it from a post on AIBU on mumsnet so I have searched the forums for an answer and despite finding a few threads on it... still no answer! Apparently she learnt the answer, or what there is to 'get' about it, from private messaging someone the answer and them telling her that she was right.
Anyway.. it is really annoying me, and I am know it should not, but I just would really like to know.
The joke/riddle:
'There once was a man called Boswell. For short they called him Bos, and he walked up the post office steps.'
Any help will be greatly appreciated. :)
