The 2015 Ig Nobel Prize Winners

The 2015 Ig Nobel Prize winners are out.  Some of the best ones:

• Physics Prize, for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds.

• Literature Prize, for discovering that the word "huh?" (or its equivalent) seems to exist in every human language — and for not being quite sure why.

• Medicine Prize, for experiments to study the biomedical benefits or biomedical consequences of intense kissing (and other intimate, interpersonal activities).

• Biology Prize, for observing that when you attach a weighted stick to the rear end of a chicken, the chicken then walks in a manner similar to that in which dinosaurs are thought to have walked.
