At the beginning of raiden's chapter, when you are first looking for peter stillman, if you go into the women's bathroom and into one of the toilets, stay there for about 5 minutes not doing anything, if you have nothing equpied, call campbell on the codec, he will say something then rose will get angry, after this try calling rose and after a bit of speech you will see some funny choices. It's pointless but it's still funny!
