Correct me if (when!) I'm wrong, but I think the "Ferret and..." chain in the UK was based on one of Tim Brook Taylor's radio comedy programmes (was it "Hello Cheeky"?)which featured a pub called the "Ferret & Terrapin".
Some new ideas...
Mouse and Trackerball
Mink & Moorhen
Queen & Camilla
Old Blair and Bush
Bullsh*t and Bush
Actuaries' Arms
Crossed Keystrokes
Banjo & Squeezebox
The Dog's Breakfast (Kim Howell's local)
Harp and Bottleneck
Pick 'n' Slide
Washboard & Kazoo (OK, no-one would go there!)
Archer and Aitken (near the Old Bailey)
Spin Doctor's Arms
Peter Green Man
...and , of course, that world-wide chain...
THE MUDCAT TAVERN

RtS
(I'll go, without waiting for me coat...)
