D is for December and Dunlop tyres, though it could just as easily be for dishy dainty damsel (even if it is a bloke) on a dyke. I mean, bike.
D could also be for: you don’t the devil say? Yes I derring-do. Because I’ve done it. Done and dusted my boat book (with a bit of bike on the side) – at least, I’ve just finished going through the proofs. So that’s darned damned dibley if you ask me. And if you don’t (ask me), then I’ll just have to Dunlop tyre the lot of you.
Dash it. Must dash. It’s December.
