I regularly listen to CNET's Buzz Out Loud. Last week, someone emailed in about headphone cords mysteriously entangling themselves. A couple of episodes later, someone else emailed about a pair of physicists winning an Ig Nobel Peace Prize by proving that heaps of string or hair will inevitably tangle. I subsequently looked up knot theory and found it strangely fascinating.
So that's the uber-geeky setup for this appropriately silly photo of the day.
