Picture it - a sunny but windy day, Mr. Ambrose Aylesbury has had his morning meal and his crop is bulging to the point it's nearly dragging, the great gut! Content at last (read: unable to stuff a single pellet more down his gullet) he waddles over to the clamshell pool, clambers in and begins splashing about with much joy. So great is his joy in the act of bathing he fails to notice he's near the edge of the pool and his head, chest and crop are standing right over the edge. With another joyous splash his great full crop of food overbalances him and he comes forward, over the edge and out of the pool still rapturousy shaking his wings, tail and body in the bathing dance - unrealizing he's actually fallen out due to his fat gut. A few more flaps and he notices (finally...) the "pool" is distinctly short of water and full of grass. He stops, looks down and looked a bit puzzled... "Hm, fancy that... I could have sworn the pool was full of water when I entered! Ah, no matter, mustn't interrupt my bath!" and continues flapping and shaking as if he were in the pool.

Silly duck. Lucky he's cute...
