It must have been very confusing in the Dark Ages. If someone said the year, 711 like seven-eleven, others must have thought about the convenience store! Maybe that's when 7-11s were invented. Their frozen burritos taste like they came from that time period.

I will say twenty-eleven. I will do it this way until the year 2020 because then people will think I'm boasting about the power of my bifocals.
