Dear Mr Aberzombie, 
Having clicked the link supplied by some random dude, I must ask the follow questions of you: 
1) Did you used to play football?  
2) Do road cones protect your head?  
3) Do you have a screen door shield?  
4) Do you like tricycles?  
5) Is there butter on your head?
6) Are you going to eat my brain? 
Oh wait, I guess you've already answered that last one ... several times ...
