Murder Spree 20
From Tardis Wiki, the free Doctor Who reference
Murder Spree 20 was an event hosted in the Icelandic city of Polar Ventura, presumably the twentieth entry of the Murder Spree series. A question on the Game Station's version of The Weakest Link asked what was the Icelandic city that hosted the event. (DW: Bad Wolf)
Murder Spree's description suggests it was a legal hosted event like the Olympics.
