Tacky, tacky, tacky

I was on a discussion forum this evening (Delphi Trivia) and someone mentioned that not only had Patrick Swayze died, but also Patrick Stewart had. I looked for confirmation, as the source was not one I'd consider completely trustworthy, but indeed, Wikipedia had today as his death date -- but it didn't have the usual header box about this being someone who had recently died. I was about to post a query once the chat ended, but I went back to Wikipedia, and the entry has since been changed, and now there's no death date.

I have no idea why anyone would consider that any sort of amusing thing to do.
