In science, it is often important not to have too big of an impression of yourself. If you are too big, you might just miss out on some interesting discoveries. Hence, the The Ig Nobel Prizes handed out for the lighter side of scientific discovery. The prizes this year included awards in Engineering (The Comb Over), Public Health (Investigating the Five Second rule for dropped food), Medicine (the discovery of a positive correlation between country music air time and suicide among whites), and Invention (Karaoke).
Just the thought of Nobel Laureates belting out "Can't Take My Eyes off of You" should show that these guys do have senses of humor.
