Holy shit, the best fucking thing happened while I was playing around with my Texas Instruments CAS calculator.

There's a random number generator on the CAS that I didn't know about, but I came accross an example in the manual of how to use it. The example shows the number generator coming up with 6 random numbers between 1 and 20.

So I decided I'd give it ago and followed the instructions, then pressed Enter 6 times, and what do you know, I got the exact same 6 numbers...
