Oscar Mysteries: Tom Hanks' Potty Mouth

Blink and you probably missed it, but today everyone's wondering who Tom Hanks was swearing at (Jon Stewart? a producer?) as he came onstage to present the Best Director award, and perhaps more importantly, what exact expletives he was firing at the target of his rage. Our lip-reading skills leave much to be desired, but we think we can clearly make out at least one f-bomb; thanks to the magic of YouTube, we can all obsess about this moment over and over again, giving this mystery the Zapruder-like attention it so obviously deserves.
