About 5 months into my current gig, I called in sick for the first time.
My excuse? I was taken to the hospital in the back of an ambulance the night before after spraining my ankle playing volleyball in the company league at the company's private park. By the time I got out of the ER, the park was locked up for the night and I couldn't get to my car (girlfriend drove me home from the ER, who did not live with me). I had no way of gettting to work until the company park reopened the next morning at 11:00.
My boss told me I had to use vacation instead of sick time.
