Our happy hour fact to amaze your drinking buddies with.

The key to getting a woman to give you her digits may be to make sure she's just heard a love song before you ask.

French researchers lured 87 women between the ages of 18 and 20 into their offices under the pretense that they would be participating in a cookie taste test. While in the waiting room before the test, the women either heard a love song or a tune that didn't touch on romantic themes.

After they ate their cookies, the test's administrator, who was an average looking 20-year-old man, read each woman a script during which he requested their phone numbers, so he could call them up to schedule a romantic date later in the week.

Of the study participants, 52 percent of the women who had heard the love song in the waiting room coughed up their digits; whereas only 28 percent who were played the neutral song did.

So there you go: A simple way to double your dating that doesn't involve mean put-downs or a goofy hat. (Oh, but you might want to bring some cookies, too.)
