Looking for a way to make up for a dip in donations due to the lagging economy, the Denver Zoo came up with an event that's both money-making and, if things go well, baby-making: the Singles Safari, a one-night party at which 500 men and 500 women wander the zoo, looking for love and stopping by various "Ask Me" stations, where zookeepers explain the horny details of polar-bear breeding and elephant sex. If the singles get lucky and become couples, the zoo also now offers Date Night, which, just like a relationship, is less focused on doing it and more focused on eating dinner by candlelight.
