Tango by Zbigniew Rybczynski.

After winning an Academy Award for Best Animated Short, Rybczynski stepped outside for a smoke and was denied re-entry from security, despite holding his newly-won Oscar. An altercation ensued and the director was arrested. His takeaway of the eventful evening: "success and defeat are quite intertwined."
