“Sarah Hird explains the need for sleep. BAHFest is the Festival of Bad Ad Hoc Hypotheses, a celebration of well-researched, logically explained, and clearly wrong evolutionary theory. Additional information is available at http://bahfest.com/” (YouTube)
This is a highly amusing video that correlates the amount of sleep mammals get with their basic satisfaction and self worth. It’s informative, funny, clearly explained, and utterly wrong, but wonderful nonetheless. Onwards!
