Wagner as a timepiece

[bloke]

You wake up in the middle of the night, for some reason you neither have a watch, a phone or a clock, and you want to know what time it is.

Here's what to do:

Pick up your tuba, take it outside, and start playing "Ride of the Valkyries".
If you get all the way through it and nothing happens, play it at least one more time. By then, someone is going to be hollering out their door or window,
"WHO THE HELL IS PLAYING A TUBA AT 3:18 IN THE MORNING ?!?!? "
