I'm totally serial. Ed is correct, the hot water will cause global warming and then we won’t have any ice. I’m totally serial.

I brushed my teeth this morning, I left the faucet on too. I got news for you, there is no more or less water on the planet now as there was this morning or there will be tomorrow.

Can you imagine the enormous amount of fresh water wasted (the cost of which is already skyrocketing in the US) should any sizeable portion of the populace begin running their taps until hot water pours out just to obtain "warmer (than tap water temp) water" for slightly faster ice cube formation? Add to that the wasted energy caused by heating the water only to cool it down again. Comparing/quantifying the inputs and savings - fresh water costs + energy cost of heating a volume of water - energy saved by not running the freezer compressor quite as long to cool it down again gives me a slurpee-like "brain freeze"!
