The trick I usually use for this is to look at my watch (which is digital and precise to the second), and taking the seconds counter, which is uniformly distributed across {0…59}. I then take option 0 if this is even and option 1 if it is odd.
(This also extends nicely to decisions with any small number of options: 3, 4, 5, and 6 are also factors of 60, so seconds modulo X is uniformly distributed across {0…X−1}. Plus, I’m not very good at coming up with words.)

An excellent alternative. I was going for something usable without any tools.
This is an excellent tip! I plan on using it from now on in my day-to-day life.
