I still have guilty feelings about one of my Christmas do's a few years ago. We all went out and got hammered, we decided to go back to the lockup (I have no idea why!) anyway we are walking back and one of the lads tripped over a brand new RSJ that was outside a house, we looked at it and thought 'who's left that there!' so we thought the best course of action was to move it.... all the way back to the lockup!
So three of us hoisted it on our sholders and trundled off down the street with it, the old bill even drove past us, they took one look and just shook there heads, laughed and carried on.
The next day when we went to the lockup and nobody had a good answer as to why we had 4m steel in there, that was cut to size for someone else.
I still feel horible about it as I know how it would have messed up some builders week
but didn't want to get caught taking it back, in any case I couldn't even tell you from where!
