A quick trip in the VP Time Machine to July 1st and back and all can be revealed
July 1st, somewhere North of Watford
Nick  "happy birthday The Boy"
The Boy: "what you got me?   That technogismothingywotsit?"
Nick  "No, something really exciting"
The Boy "what from that holiday in the sun you had (and never sent me a proper postcard"?"
Nick  "no, something no one has ever had as a pressie before and will really frighten anyone you show it to"
The Boy:  "cool, gimme it then"
Noises of rustling paper as the package is unwrapped
A scream is heard
The Boy:  "Dad what the fuck is that?"
Nick  "your new pet . . . . . . . . Giant Mutant Maggotus Casserollus . . .  .aaarrgghhhhh"
The Boy:  "Dad it's bitten your left hand off, you'll have to be a rightie now"
