An Englishman, an Irishman, and a Scotsman walk into a bar

and spot a Welshman sitting alone at a table.

The Scotsman said to the others, 'Let's pick a fight with that Welshman over there.'
The Irishman replied, 'Wait, we don't want to be arrested. Let's make him start the fight.'
The Englishman said, 'Wait here chaps. I know how to do it.'

He went over to the Welshman and said, 'St David was a flippin' sissy.'
To this the Welshman replied, 'Ah well you don't say!' and calmly resumed drinking his beer.

The Irishman now tried his luck and said to the Welshman, 'St David was a stupid fool that wore a dress!'
The Welshman again replied, 'You're very sharp, you don't say!' and calmly resumed drinking his beer.

The Scotsman told his friends he knew how to rile the Welshman and bounced up to the table and yelled, 'St David was a Scotsman!'

The Welshman replied, calmly, 'That's what your mates were trying to tell me.'
