You see Costas, that's why you'd make a crap evil genius, you're swayed by realism.
I want a massive rocket attached to a flimsy trailer that could be towed by a suitable evil camouflaged Fiat Panda convertible. I'd paint a nuclear symbol on the rocket's red nose cone and my evil army's roundel on the fins. I'd apply a two-tone camo which looks military but has no bearing on the surroundings and I'd have a conspicuous box with red flashing lights and an Irish alarm clock read-out so that it's constantly counting down to something. This would be the trap - they'd be three wires in that box, one red, one green and one white. None of them would be attached to the warhead in any way, but all three would be attached to my central security alarm system. [evil laugh....]
