My first failure came when I failed to create the promised Grandfather Paradox post immediately. My second was when I totally forgot my login details as I tried to create this post. My third is happening now, as I have lost interest in explaining the paradox, so I'm not going to bother. Check out the comprehensive Wikipedia entry if you're interested. Chaos, chaos, all is chaos! Fabulous.
I do actually have something to say today, but I'm going to create another post under an appropriate title - or will this be my fourth failure?
