A man walks into a pub, sits down at the bar, and says to the barman, "cor! I've just had my first blow-job and it was great! -- I'll have a large whiskey please, barman." The man takes his whiskey and downs it. "Same again?" asks the barman. "Okay" says the man and downs the second. He then orders a third and a forth and downs them both.In fact in total he downs 27 whiskeys. "Do you want another?" asks the barman. "No I don't think so", says the man, "If 27 whiskeys won't take away the taste I don't think that another one will!"
