Well this one goes in my favour. Every time I approach a crossing on the way to work (if cycling), the light by McDonalds turns green. it happened so mnay times (well, every time actually) that I tried to figure out of there was some sort of sensor on the cycle path that stopped traffic for me. I couldn't find anything though. No-one was pushing the cross button either, because no peds were at the crossing.
Now I've said it out loud of course, it won't happen again
