I'm going to make fun of all the people that wait until 2020 to switch because it sounds cool instead of doing it now. I also kinda want to live to see 2110 to see if there's still people saying "two thousand one hundred and ten". Thirdly, I'm pretty sure my kids will call last year "twenty oh nine" and we'll sound like old people saying "nineteen hundred and aught five" instead of "ninteen oh five" to them, though my mom is convinced they'll come up with something completely different. Fourthly, Bill O'Reilly calls it "two-ten", incidentally. Fifthly, does anyone else find themselves saying "oh-ten" for the abbreviated form, as in Class of '10, like '09, etc.? I'm doing it semi-intentionally at this point, since I feel like it's going to be a while before the last two digits on their own sound like years again rather than just numbers, and we've become accustomed to years starting with oh. And there still is an 0 before it, anyway.
