1UP has an excellent summary of Tuesday's tomfoolery across the Web. The site ranks pranks on a scale of one to ten Shia LeBeouf because the dudes at 1UP are certain that "Shia LaBeouf is probably a big jerk."
I think that's a pretty safe bet.
I do heartily agree with the WoW and LoTRO pranks ranking only 4 Shia LeBeoufs each. I found them both really funny, but neither attempted to fool gullible spectators. The WoW prank from two years ago was pretty good. I remember people getting really pissed off at the prospect of playing a "wisp."
