Our happy hour fact to amaze your drinking buddies with.

The much-maligned withdrawal method is basically as effective as condoms in preventing pregnancy.

In a study published in "Contraception" magazine, researchers found that if the male always uses the withdrawal method 96 percent of couples won't become pregnant over a year, as opposed to the 98 percent who always use condoms.

But those are rates for when couples execute these methods optimally. For "typical use" the yearly percentages are even closer -- 82 for withdrawal and 83 for condoms.

Another way to ensure you will never get a woman pregnant is to wear a fanny pack on all your dates. If you don't believe us, try it.
