In the Minnesota Zoo's Tropic Trail, there's a Komodo dragon enclosure and next to it is the combination waterfowl/flamingo/lagoon with the gibbons on the island (gibbons HATE water, and will avoid it like the plague, so you can effectively isolate them on islands and have a combination exhibit that looks slightly more natural). Anyway, sometimes one of the flamingos will accidentally find its way into the dragon enclosure during the night. The keepers usually find out about this in the morning when they come in and there's a scattering of pink feathers on the dragon's sand. For being giant generally-slow-moving lizards, those suckers are damned fast when they want to be.
