Getting back on the original tack how about these:
Northrop X-55 Ascender which was a jibe on the fact it had the prop at the back (Ass Ender).
Sopwith Dolphin which was not a seaplane!
Sopwith Cuckoo which I suppose threw all the other aeroplanes out of the hangar?
Hawker Hedgehog - a ground attack aircraft maybe?
Hawker Humpback - had a whale of a time
Fairey Ferret - a partner to the Hawker Hedgehog?
B.A.T. Baboon - words fail me.......
