I once watched a pregnant woman jaywalk causing both lanes of high traffic to stop. She went halfway across the road, apparently realizing that she was causing a problem, so she turned around and slowly waddled her way back to the other side. Only to then realize that she still wanted to cross the road and so therefore turned around and interrupted traffic yet again!

Needless to say, soliders quickly resolved the traffic incident but it was funny and frustrating to watch at the same time.
