Lost Key

This morning I got up at 3:15 AM to go running 16 miles. Around mile 13 I had to pee. It was very dark outside so I just went there on the side of the road. (green with envy for all you males standing all nonchalantly on the side of the road) When a car started coming I quickly got up and tried to pull my shorts up. In doing so I lost my key which had been in a little pocket. The ladies I was running with had gone ahead and I had to call one of them back to use her headlamp to try to find it. No luck. So we started running and I was thinking how much it was going to stink to get to my car and not be able to get in. After a short distance something scurried across the road and it made me and another lady jump. When I jumped I felt something odd... in an odd place. My key was in the spot between my underwear and the pre-installed underwear of my running shorts. Now when I lose something the ladies say "Did you check your underwear"?
