Hi.  Looks like someone hacked in and messed up your page on John McCrae.  Or maybe they just logged in and made the changes, although I'm pretty sure Wikipedia has some sort of peer review process... 

 On the first page, at the end of the last sentence, you'll find "and also ate deez nuts".  His last name was changed, over the photo of him, and within that box, the last entry for "Known for" says "...and Deez Nuts". 

 Probably just some kid feeling frustrated over having to do a stupid meaningless assignment, but it's a shame, especially on Remembrance Day.
