What's a good excuse?

When Annie first started her exercise blog, she did an awesome series on excuses. People will always come up with great excuses to put off exercising until tomorrow. Well, I am currently fighting a moral battle with myself. This morning, I had to go to the dentist because I lost a filling. Well, my quick exam turned into a 1.5 hour root canal. My first. I tried to go back to work after, but realized 1) I couldn't talk, 2) I was a drooling mess, and 3) as the novocain wore off, the pain started. So I promptly went to Walgreens, got my antibiotic and pain med prescriptions filled, and came home. I passed out for 4 hours, waking up to that lovely, swollen, throbbing pain on the left side of my face.

So, now, the question remains: DO I RUN?
