hahahaahahahahah
I don't get it 
I wonder if he'll ever become more public about his identity. Certainly, at the very least, he's a funny guy.
It's the "within the next 25 years" part that makes the quote funny. Representing time with a signed int doesn't become a problem for a long time, so Satoshi was being sarcastic.
Am I the only one who finds this quote funny? Maybe it needs more context.
I found it funny, but that's because I have background in Unix timekeeping and C jargon. I assume the average person doesn't have this knowledge, and therefore it would not make sense to them.Am I the only one who finds this quote funny? Maybe it needs more context.
I also found it funny. Doesn't need more context right now, but maybe when "commoners" adopt Bitcoin...
@BTCurious It took me 2 full seconds to get it. I can't believe it took that long! Good job. Would buy again.

A signed integer can be either negative or positive (- or +), such as 55 and -55. An unsigned int can only be positive. If you only need to deal with positive numbers, you should use unsigned ints because the maximum integer number the type can hold will be twice as much as a signed int.
Correct.
We could get into the amount of values it can hold, but that maybe a little more advanced (like a 64 bit unsigned integer).

What is a signed int and why should they be unsigned, according to Satoshi?
