Hey Buddy

An American was cruising through Co. Tyrone in his Cadillac when he stopped on die Carrickmore to Omagh road to watch the turf-cutting.
'Hey buddy,' he said to Liam, who was leaning on a fence, 'what's that little old machine over there?'
'That's our turf-digging machine,' said Liam.
'Really? Why, back in Texas we have spoons bigger than that,' said the American.
'Aye, but look at the size of your gub,' said Liam.
