Over the counter

A middle aged man, about 5 foot 8 inches tall, walks into a Walmart and asks where the pharmacy counter is. He is directed to it. When he reaches it, he asks to see the pharmacist. The pharmacist comes and the man, looking around furtively, asks quietly, "Do you sell Viagra here?" The pharmacist answers firmly, "Yes, sir. We certainly do." The man then asks, "Do you think I could get it over the counter?" The pharmacist thinks for a moment and then says, "Perhaps, if you took five or six pills at once you might."
