In Hiding

An Englishman, an Irishman and a Scotsman had escaped from jail and were being followed by The police with tracker dogs. They decided to climb up into The trees to escape detection. As The dogs came sniffing at The base of The first tree, The Englishman, went 'miaow, miaow.'
'Come away,' said The policeman to The dogs, that's only a cat.'
'Chirp, chirp,' went The Scotsman.
'Come away,' said The policeman, 'that's only a bird.'
The dogs then began to sniff at The base of The tree where The Irishman was hiding.
'Moo, Moo,' went The Irishman.
