A bloke is having trouble maintaining an erection. He's tried cure after cure but nothing works. In desperation, he visits a Chinese herbalist. He's given a small vial of powder and the following instructions, "Sprinkle on dinner, when comfortable in bed, say, 'one, two, three.' You will be able to perform for as long as you or your wife desire. When you are satisfied, you or your wife just need to say, 'one, two, three, four.' But, be aware that once you say that, the powder will not work for another twelve months."

So the chap rushes home in great excitement. At the dinner table he sprinkles the powder as directed then can hardly wait to get to bed. When he and his wife are settled in bed, she gives him a peck on the cheek, then turns her back to him and snuggles down under the covers.

He waits for a few seconds, takes a deep breath and counts, "One, two, three." Just as he starts to feel arousal, his wife turns to him on one elbow, and asks, "What did you say .one, two, three, for?"
