And opposite the 'Frog and Nightgown' on the Old Kent Road is 'The World Turned Upside Down'. I've seen a few 'The Case is Altered' as well (used to be a good one near Leamington with an old bar billards table that only took sixpences), but don't know where the name comes from.
There is an "Athletic Arms" opposite an grave yard in Edinburgh (known localy as The Diggers) and there used to be a "Ferret and Trouserleg" but I think it's closed now but my favourites are the Firkin chain if only because of the bar staffs T shirts "I'm a Firkin Barsteward".
Adding to my own question, here! There's a pub in Dulwich Village (South London) called The Crown & Greyhound but it was always known as "The Dog & Vomit" by all & sundry.
