Englishman and an American

On a train from London to Manchester, an American was telling off the Englishman sitting across from him in the compartment.
"You English are far too stuffy. You set yourselves apart too much. Look at me... in me, I have Italian blood, French blood, a little Indian blood, and some Swedish blood. What do you say to that?"
The Englishman replied, "Very sporting of your mother."
