Why does my Mac power adapter spark?

When I plug my MacBook Pro Power Adapter into most/all outlets, I see a blue spark as the prongs enter the outlet. Is this normal?

I see and hear a spark every time I plug my MacBook Pro power adapter into an outlet. I'm using the standard two prong charger seen here
. I think the sparking is a new thing. I don't remember this happening regularly before; I bought my MacBook pro two years ago. What causes the spark? Should I be worried about my charger (and ultimately, my laptop)? Does anyone else have this happening with their power adapters?
As a precaution, I make sure to plug the adapter into the wall before I connect it to my laptop.
For reference, the spark seems bigger than a standard static electricity spark.
