Read them all.
Two Irish traveling salesmen(are they still called that I wonder)are on a train together with a British tourist riding in the same car.
The conversation between the two Irishmen went on like,
"I've been to Killpatrick, Killkenny and now I'm on my way to Killmainham",
and the other replied,
"Oh, I've been to Killshaw and now I'm off to Killmore".
The Brit who had been listening to this exchange with mounting horror suddenly got and made his way out of that car thinking to himself "murdering scoundrels".
