Google's most mysterious SERP

One of the developers of Beerby (a program for beer lovers) drew attention to a strange fact : the site receives unusually a lot of search traffic for [ cake central ]. He checked and was horrified: the absolutely left page ranks first in Google search results, ahead of cakecentral.com sites and more, despite the fact that CAKE or CENTRAL are never mentioned on this page .

Question to the optimizers: how is this possible and how can this glitch be reproduced on another request?
