Bamse: Yep, that's it.
Okay, how about this: a while back I worked on a construction site where there was a lot of employee theft. A friend of mine was implicated, and the security guards were told to keep an extra close eye on him. Every night he'd pass through the security checks with a wheelbarrow filled with discarded electrical wires, offcuts of scrap lumber and chunks of concrete. The guards checked the contents every day, but they never found anything of value. What was my friend stealing?
