1) one black cd marker pen i borrowed from oxana's desk (i'll put it back)
2) one a4 sized sheet of paper stating: "i am a basketball. sign me!"
result: 37 signatures (some even containing little drawings) in one day.
interesting. nobody knew who put the ball there and what dark plans he/she had with it and the signatures on it. in case you were wondering, it now serves as a private green kong for the 'most successful bay' in sqe, the first recipient is juliane.
