Justin Bieber launched himself back into the news this week by writing something totally idiotic in Anne Frank's guestbook. No one should be surprised. The Biebs fills his Twitter timeline with some of the most inane chatter on the web. The only thing stupider than his tweets is the number of re-tweets his fans give him. Whether those fans are actual people or just bots is up for debate, but one thing is for sure: if these people are real, they are a bunch of morons. Below is a sampling of just a handful of totally meaningless Tweets that each garnered at least 50,000 re-tweets. It's all the proof you need that Beliebers are unbeliebably stupid.
