原创 How many seconds does it take you to solve this?

It's no secret that I am a huge fan of The Big Bang Theory TV show. In fact, I love it so much that -- now the eighth season is over -- I'm watching the entire thing from the very beginning. It's amazing how much you forget. For example, do you recall what Leonard and Sheldon were doing when we first meet them at the start of the very first episode?

The reason I'm waffling on about this here is that I was meandering my way around the Internet as is my wont when my eye was caught by the image below. The contents of the whiteboard are obviously superimposed onto a scene from the show, which couldn’t fail to intrigue me.

STOP! Before you look at the puzzle in the following image, glance at your watch, and then see how many seconds it takes you to solve this cunning conundrum.

Please don't post the answer below -- let's not spoil the fun for the next person to see this blog. On the other hand, I would be interested to know how many seconds it took you to solve the puzzle.
