Bag Of Ducks
One Kerryman met another carrying a bag on his back.
'What's in the bag?' asked the first Kerryman.
'I won't tell you', said the second.
'Go on, do'.
'All right then, it's ducks'.
'If I guess how many ducks you have in the bag, will you give me one of them?'
'Look', said the second Kerryman, 'if you guess the correct number, I'll give
you both of them'.
'Five', said the first Kerryman.
