Cera, Gaby Hoffmann, and Director Sebastian Silva made a very funny, surreal movie about a drug-fueled road trip. The stories behind the film are even wackier.

The floating turd in the opening scene? Silva laid that.

They spent all night filming a wild party (filled with cocaine, dancing, and the works) and it was crucial that they had a sizable log; it's actually an important device to explain Michael Cera's character Jamie.

All night, Silva tried to get people to pinch a loaf in the bathroom, but no luck. By 6 a.m., he was desperate, and went into the bathroom himself. As the director tells it, he ate nothing and had to squeeze as hard as he could to create what he termed the "miracle turd."
