A:
I did my first chin-up today!
B:
Nice man, good for you.
A:
Yeah, thanks. If you graph the age at which someone does their first chin-up, I'm sure being 28 puts me in like the 99% percentile, haha.
B:
Yeah, I'm sure. You're 28?
A:
Wait. No, haha, I'm 27.
B:
Ok, I didn't think you were that much older.
A:
Whoops! But yeah, I'm actually a little proud of myself, I. Wait. No, I'm 26.
B:
... Do you really not know how old you are?
A:
No way, man. Why bother? I've already got my birthdate memorized, I can just calculate my age on the fly.
B:
Except you can't.
A:
Well, I got to it, it just took a bit. It was easier before the Millenium, I used to be able to just drop both one-nines and do 99-83 or whatever. Now I have to drop the two-zero, then add one hundred, then drop the one-nine, and subtract that. So it takes me a little bit sometime. But still, you gotta admit. It's convenient.
B:
I think the next time you don't know your age and someone calls you on it, just say you have a concussion.
