From How to Overcome the Fear of Rejection: The Successful Rejection Experience by Jonathan Robinson, MA, MFT:

. . .Fortunately, each rejection got easier. In fact, I soon noticed that the women I spoke to seemed more nervous than I. My rejections were proceeding rapidly and smoothly until the seventh woman I approached. When I asked her for a date, she said, "Sure." I hadn't thought of the possibility of someone saying "Yes," so I said, "Sure what?" She finally convinced me she really wanted to go out with me. I wrote down her number, and in a state of happy amazement, soon asked another woman for a date. To my surprise, she also said "Yes." By this time, I was feeling totally at ease while I asked women out, and they frequently responded by giving me their phone number. In fact, after a while I had so many dates that I had to begin acting like a jerk in order to fill my quota of ten rejections (and get my $50 bucks back). . .

Cute, eh?
