I can sympathise with old Lt Pigeon. Just after lunch I always get a little dozy too. Either that or he's just seen it all so many times before. I hope not for as Dr Johnson almost said "when a pigeon is tired of London he is tired of life..."
you know what I have never really thought about the fact that pigeons sleep. Must say not over fond of pigeons, can't remember who said it but it was spot on, pigeons are rats with wings
