The bigger fuse thing reminds me of the guy at a German board who had a standard electric kettle and took measurements whether the water boiled faster if the cooker was on a 25 Amp circuit instead of the required 16 Amps. For that test he simply overfused one of the circuits in his apartment... and then he had some (unrelated) trouble with his fuse box. Somebody asked "What on earth is that 25A fuse doing in there???" and that guy sheepishly answered: "Well I was checking if the water boils faster on the bigger fuse..."
Believe me, that was the laugh of the day!
