While it's a scientifically-proven fact that humans require food, water, air, and shelter to survive, it is not yet widely known that straight men also require eggnog post-coitus in order to continue existing in this wild world of ours. So this summer, please don't bring a six-pack of beer to your neighbor's barbecue. Instead, tell him that you value his post-intercourse survival and bring him several cartons of refreshing, summery eggnog. His life may just depend upon it.
