The title is pretty much self-explainatory, for those who didn't read it. you mention an event and you lay the link to another event an example;
'Playstation network went down and a few days later Osama Bin Laden was found and killed by Navy SEALS'
The conclusion*: Osama Bin Laden owned a PS3.
*The conclusion is optional.
both real and Fictional events are allowed
Sorry if i offended someone with this example.
