The worst thing I ever posted wasn't when I was sick, but it was when I was like 13 (that explains a lot right there). Old-school message board (predecessor of today's forums). They supported HTML coding. I posted an ASCII picture of a middle finger. . .surrounded by the <marquee> coding so it flew across the screen from left to right. Hilarious at the time, but, yeah. Nothing like a middle finger flying across the screen repeatedly. Actually, that's still a funny thought, even today, haha.
