Johnny (as I think he loves making jokes) keeps in a hand one dirty absorbent (I think a girl may be helpfull for this one ;) pretty heavy menstruations are needed ). It doesn't have to be "fresh", it should be a little bit old (probably the smell will get worse with the time)... Johnny, furtively, goes behind somebody (of the crew, obviously) and slaps the absorbent on the guy's face (preferably on the mouth).... The reaction won't be so good, so a cup or something like that wouldn't be a bad idea :)
