First off, Mat, you didn't flick any fuses whatsoever, you smug git. In fact, Mat, you're wrong.
If there's something with a switch on it and flicking it makes your lights come back on the fuse hasn't blown, the MCB has tripped. They probably do call them fuses on the instructions to avoid confusing the technically inept, but they're not. So there.

On a lighter note, you're probably in for a spanking anyway, and other things besides, just for being in Jennie's house...
