This is what happens when too many anxious fanboys gather in one place. One man allegedly stabbed another near the eye with a pen Saturday in front of 6,500 people at Comic-Con in San Diego. The attacker, wearing a bloodied Harry Potter T-shirt, was subdued by members of the audience before being led away by police. The victim suffered a minor cut around his eyelid. The scuffle began between discussing panels for Resident Evil: Afterlife, and the two upcoming films, Paul and Cowboys and Aliens. Comic-Con is the largest comic book and pop culture convention in the country.
