Gary glitter joke
--------------------------------------------------------------------------------

Gary Glitter is facing death by the firing squad.





His last wish was for Peter Crouch to take the shot




However, as it is a firing 'squad' (Rafa, it's pronounced skwod not skwaaard) there would need to be, surely, more than one person taking shots.

Nice joke, technically flawed though.
