I know I'm coming late to the party, but Willy on Wheels is hilarious, as is the Wikipedia tribute page: http://en.wikipedia.org/wiki/Wikipedia:Vandalism_in_progress/Willy_on_Wheels
And I remember when LMS threw a hissy fit because I was preserving home page vandalism, out of fear it would only encourage them. People these days are doing a better job than I ever could.
Shouldn't this be in Bad Jokes and Other Deleted Nonsense?
