8. Herman Cain, on Libya

Who amongst us hasn't suffered from some sort of temporary mental lapse at an inopportune time? We've all dealt with struggles to recall certain passingly important facts before friends, family, and coworkers, and failed miserably.

"Uhh, I've got all this stuff twirling around in my head," is fine to hear from a friend in the wake of a smoke session, but far from reassuring in between uncomfortable pauses from a presidential candidate talking about he'd personally handle Libya's uprising.
