An Englishman, a Welshman and an Irishman

An Englishman, a Welshman and an Irishman are taking a trip of a lifetime, across the British Isles. As they drift slowly across the green fields of Wiltshire, John, the Englishman, pours a pint of finest Ale out of the basket.
"What are you doing?" asks Dai, the Welshman.
"It's ok," replies John, we have loads of it in our country.
A few hours later, the drizzle sets in. They cross over the Bristol Channel, and find themselves choking in the mire above Port Talbot. Suddenly Dai throws a sheep out of the basket.
"What the...?" asks Paddy the Irishman.
"It's fine," says Dai, "We're over Wales. We have loads of sheep here."
They drift out over the sea, and as the sun sets in the west, they come upon Wexford, in the south east of Ireland. Standing there admiring the view of the Green Isle, Paddy throws out Janek, a former native of Warsaw.
"Hey, what's the big idea?" asks John, the Englishman.
"It's ok, we have loads of them over here."
