I got the name Penfold for my male chocolate Burmese from watching Danger Mouse. Penfold was DM little sidekick in the dark blue suit, whenever anything went wrong he'd say "Oh crumbs".
Whenever Penny (his nick name) tries to tightrope walk along the fence line (Which anyone with a chunky male Burmese will know, they don't do gracefully). Or has been busted for doing something wrong, he looks as though he's muttering that very punch line "Oh crumbs"!
