We’d like to say this is an August afternoon prank, or the monologue for late-night TV, but it appears to be for real. According to Fox News, the FBI has issued a bulletin warning of possible “acid-filled eggs” at the Republican and Democratic conventions.

The warning, issued by the FBI with the Department of Homeland Security, has an attention-getting title: “Potential for Violent or Criminal Action By Anarchist Extremists During the 2012 National Political Conventions.”

In addition to the possibility of the tainted eggs, the bulletin warned that protesters might also try to block roads, mess with transit systems, and use Molotov cocktails to disrupt the conventions. We called the FBI for comment but have not heard back.

The GOP convention begins Monday in Tampa, and yes, there is also the chance it could get hit by Tropical Storm (and maybe by then, Hurricane) Isaac, which is now moving northwest through the Caribbean.
