Two English businessmen in London 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 idiot 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 Scotsman walked to the window, had a peek, and in a thick Scottish brogue  asked "What might ye be sellin' here?"

One of the men replied sarcastically, "We're selling ass-holes"  

Without skipping a beat, the Scotsman said, "You're doing well...only two left!"
