h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This is a variant on the Monopoly Board pub crawl, but using Circle Line stations instead of Monopoly properties. I discovered its existence while having a quiet drink in a nice little pub near Aldgate. It got considerably less quiet (and a great deal more interesting) when invaded by a group of twenty-somethings in matching T-shirts who all ordered a pint, downed it and headed out again, followed approximately 3 Tube minutes later by a second group who did the same thing. The giveaway was the T-shirts, which were emblazoned in large friendly letters with "Circle Line Pub Crawl" and the names of all the pubs (and their nearest circle line stations) to be visited. Presumably these are to enable even the most dedicated drinker to remember where to go next. Until they're too drunk to read of couse...
