What I learned in the Funny Times today

I am amazed! I read in the Funny Times this morning that there is an official Law of the Natural Universe that goes like this...

Variation Law: If you change traffic lanes, the one you were in will start to move faster than the one you are in now (works every time).

I always thought that was just me! So what happens if two of us change lanes into opposite lanes at the same time? Huh?
