Discworld II: Rincewind say “F**k“

It’s a well known fact that by entering the Elf Kingdom you could access four easter egg scenes in which Rincewind meet himself from the previous. There is however a less famous fifth scene in which Rincewind say “F**k“. In order to access it you need to use the Suffrajester twelve time on Rincewind, in the twelfth time Rincewind would change his response, now you could active the easter egg as before (i.e each fifth time you enter) and the cut scene would randomly appear.
