So I used to work at this office...
In the middle of the office was this huge copier...
Right next to the copier was this tall stack of printer paper...
Well, one day I brought in this little set of bongos and put them on top of the tall stack of paper...
Later that day one of the other employees came up to me and said, "Andy, why did you put bongos on top of the printer paper?"
I looked at him and said... "it's for when the paper jams."
