Explain what "proving dead" is please. The mouse certainly was in my opinion but I am not a vet.
But a snake in a CU. Now that is brilliant. You tell the customer that it is probably nothing to worry about, open their CU and then tell them it is only a dead snake that was causing the problem.

That process of checking that conductors or equipment that you are about to work on and that you /think/ you've isolated *really* is dead. A proper formal procedure (e.g. to comply with the EAW regs) involves using a test lamp or voltage indicator and proving that the indicating device itself is working both before and after the test.
Plenty of hits on Google, e.g.
Making sure that a circuit is disconnected before working on it.

15 off kV at serious currents. Lotsa charged capacitors that would regain a bit of charge. One bloke thought he had gone through the "SIDE" routine Switch off, Isolate, Dump the capacitor charge, and Earth
Except the Isolate weren't done and someone as a temp measure had inadvertently bypasses the switches. A most amazing BANG!!!
Gave the poor sod such a fright and the rest of the factory some amusement....
The message from tony sayer contains these words:
Ah yes, that's a nasty habit of capacitors, isn't it. TV tubes can do the same. You earth the HT nipple on the side, then a few minutes later the sodding thing's live again - you know this 'cos it's given you a heck of a belt.
More like a 1/2p at the most (if anyone remembers those!
