From the press: "Father arrested for serving a headbutt to his daughter's high school principle". I find it amusing for two different reasons.
First is the actual choice of the father to use his own head as the instrument of assault. It seems, in general, that there is an inverse correlation between one's intelligence level and one's tendency to employ headbutts. It's as if they are saying "well, I ain't got no use for this big heavy organ anyway, might as well use it as a weapon". Think about it - when was the last time you've seen a physicist, for instance, headbutting someone?
The other amusing fact is that the newspaper chose to specify the sort of blow that has been served to the principle. Would they have named the type of blow had it been a knee blow? an elbow blow? an uppercut? I sincerely doubt it. So why explicitly name the blow a headbutt? Why not just say "father arrested for assaulting principle"?
Oh, well. I'll go practice my headbutting technique now.
