In a flat in a pillar box somewhere in Mayfair, lives a white mouse with an eyepatch who is the world's greatest secret agent and his cowardly incompetent assistant Penfold who is a hamster. They get their orders from their confused spluttering boss Colonel K what he is exactly I'm not sure possibly a walrus, and every episode they fight the forces of evil waiting to take over the world usually it's evil toad Baron Silas Greenback with his pet caterpillar Nero and henchman Stilletto an Italian stereotype crow though other villains do appear. It's as barking mad as it sounds, spoofing classic British spy films brilliantly voiced by David Jason as Dangermouse and Terry Scott as Penfold who seems to be scared of everything and is every bit as good as you remember watching as a kid. Sheer inspired lunacy with the characters seemingly aware that they are in a tv show and can hear the narrator though it can feel a bit samey and predictable after a while. One of the best cartoon series ever made.
