A streaker and a book-throwing protester? Surely President Obama has seen it all by now. The scene yesterday at a Philadelphia rally hosted by President Obama and Vice-president Joe Biden was reminiscent of the 2008 elections, except when someone decided to throw a book at the President (at the 00:21 mark in this video). But it's not yet clear who threw the book and why. What is clear is that a 24-year-old man named Juan James Rodriguez attended the rally in the nude, with the words battlecam.com written on his belly. Rodriquez is trying to claim the $1 million offered by British billionaire Alki David for the first person to streak at an Obama event, reports Gawker. "I like Obama," David told the New York Daily News. "This is just a prank." Luckily, President Obama didn't seem to notice the flying tome. What do you think? Did the prank go too far?
