Around 1961(?) - I was maybe 14 - I tried to measure the high voltage winding of a surplus power transformer. I had only the wire colors to go by, but I "knew" that black was always the primary so I wired that to a power cord and clipleaded the meter to the red HV leads.

I was right about red, but the black wires turned out to be a 2.5v filament winding. My meter acquired a curved needle and never worked again. Blew the house fuse so I could not disguise my mistake from mom...
