A.A. Milne - Cottleston Pie lyrics

Cottleston Cottleston Cottleston Pie, A fly can't bird, but a bird can fly. Ask me a riddle and I reply Cottleston Cottleston Cottleston Pie. Cottleston Cottleston Cottleston Pie, Why does a chicken? I don't know why. Ask me a riddle and I reply Cottleston Cottleston Cottleston Pie. Cottleston Cottleston Cottleston Pie, A fish can't whistle and neither can I. Ask me a riddle and I reply Cottleston Cottleston Cottleston Pie.
