Rules are simple, one person posts a picture and you have to then post a picture that destroys or cancels out the above posters.
For example, If I posted a picture of an ice-cube, the next poster could put a picture up of fire... as it melts the ice.. . then a firefighter would destroy fire, unemployment destroys a firefighter and so on...
I'll start with this one...
