A Scottish Joke

A Scotsman was traveling to London, and a rich man accompanied him in the carriage. Every time the train reached a station, the Scotsman would get off, disappear for a few moments, and return. This preyed on his companion's mind, and he asked him: Are you ill? Can I help you?

He answered: No, I am not ill, but I have a weak heart, and I fear I may die suddenly on the way — and then the price of the ticket would be wasted!!
