The early days of Illogicopedia were characterised by really bad one-liners, little experiments in pseudo-vandalism and jokes you wouldn't dare put in a Christmas cracker. Head Hitting Illogicopedia fits into all three of these categories rather nicely, and served as an early parody for the 'Editing Illogicopedia' page. Editing > head hitting, geddit? I'll bet you wish you didn't.
Note the article's placement within the Locigal category (highlighted in the above image), which was massively popular in the very early stages of the adult Illogicopedia. In case you didn't know, that's when it grew spots, armpit hair and a liking for toilet humour - around February 2007 for the completists. Incidentally, that's round about the time it flunked its driving test and smoked its first cigarette (an exploding one given to it by Bcbkye).
Though relatively weak, the pun was warmly received by a grand total of four users; its creator, Fluffalizer and three vandals. This was reflected in a tribute, Hitting Illogicopedia's Head, which extended the joke just that little bit further and squeezed out what remaining life it ever contained.
