It's a rather fuzzy photo... The black on the finger is not dirt but bruising.
You see, A couple of weeks ago, the battery in Marj's car died so I took her to church early (she was helping with lighting), then stopped for a battery on the way home.
I got home and started to put in the battery before Kyle and I had to take off. I went to pull the trouble light off the shelf and started pulling another bulb along with it. Reflexes took over and I went to catch the bulb... In the process, I slammed my finger into the air compressor. OOOUUUCHHH!!!
Kyle and I changed the battery. Sometime around the middle of church, I realized it was getting quite swollen and, after church, got a glass of ice to soak it in.
The good news, it wasn't broken... The bad news... It was black, blue and green for about 4 days.
