The title is taken wholesale from this story by ESPN which is very interesting. The most interesting part of it is the fact that Red Bull took fourth in Spain with Webber by sending out a dummy call for him to pit. Alonso pitted while Webber drove past into fourth. The story is that Alonso pitted at the same time as Webber throughout the race covering his position - until they were sold the dummy that is.
How did Ferrari know when Webbo was coming in? That's what Horner is hoping to find out - RBR is holding an internal investigation. RBR have changed their pitstop procedure for Monaco as a result.
