A Welshman, an Englishman and a Irishman were being chased by Farmer Giles with a shotgun. After 10 minutes of running they spotted a barn and ran inside.

Once inside they each hid in a old sack against the barn wall. The farmer went into the barn but did not see where they went, he was about to turn back when he saw three suspicious looking sacks. He walked forward and prodded the first sack with his gun. The Englishman inside said... ''Meow'.'

"Just cats," he thought.

He then prodded the second sack. The Welshman, hearing how the Englishman got off said... ''Woof'.'

"Just dogs," he thought.

As he walked towards the last sack, the Irishman worked out what he was going to say. As soon as the farmer prodded his sack he said... ''Potatoes!''
