Everything in XKCD is based on truth. That’s what makes it so funny… to geeks, at least.

He also put 33 instead of 33 and ⅓. Get the pitchforks!

Just a random thought, I always knew that 33 multiplied by 3 is 99 and 33 1/3 multiplied by 3 is 100, but I never considered that 33 is 99% of 33 1/3.

Oh my god I’m full of caffeine and still wondered this same thing. In my defense it’s Friday afternoon and I’m tired.

Yes, you’re dense lol. The speeds are correct: the second hand that does one full Revolution Per Minute, the minute hand does one full Revolution Per Hour and the hour hand does one Revolution Per 12 Hours.
