re: Hot water from the tap, do you use it to cook?

Cold water.
I had a science teacher in high school that said cold water would boil faster, no idea of the science behind this and I never tested it.

Hot water definitely boils faster, that's pretty basic stuff. The rate at which it boils depends on the differential between the liquid temperature and its surrounding temperature.
Anyway, I use the hottest water I can get from the tap all of the time to boil because I don't feel like waiting.
I obviously don't do this for something like rice, however.

This is not true. You have 120 deg water and 70 deg water, you add the same amount of heat, which one reaches 212 degs first?

As did I until I grew up and learned about actual science.

I once worked with a guy who swore that putting hot water in an ice cube tray would freeze faster than cold tap water.
I looked at this idiot like he had 2 heads, and both of them were on backwards.

Physics tells us this is wrong, but many people persist in believing "alternate facts". Another is that previously-boiled water freezes faster. A popular belief is that water in altered physical states can have special health benefits. You can buy devices with the promise of generating such special water...save your money.
Ironically, physics or confusion about physics is behind some of these beliefs. Liquid water is a mix of molecular chains shifting among configurations in a small fraction of a second. Different mixtures can have slightly different properties. For unusual mixtures to persist requires highly modified experimental environments.

bullshite... What kind of science is that?
The hot water here is dam near boiling hot
