That feeling, when your stomach drops out the bottom of your shoes when you realize what you've done. If only run around the earth real fast, and go back in time. As you say, nice when you can laugh about it later. Not quite as easy on the day.
I've done a few of these myself. Even been set up by 'friends' on the phone. Stomach still goes out the tennies, no matter what.
Thanks for a fun story, enjoyed it muchly.
