Two London businessmen were sitting down for a break in their soon-to-be new store. As yet, the store wasn't ready, with only a few shelves set up. One said to the other, "I bet any minute now some thick tourist is going to walk by, put his face to the window and ask what we're selling." No sooner were the words out of his mouth when, sure enough, a curious Lancashire man walked to the window, had a peek, and in a broad Lancashire accent asked "What's tha sellin' ere?" One of the men replied sarcastically, "We're selling arse-holes." Without skipping a beat, the Lancashire man said, "Tha's doing well ... Only two left!"
