People don't actually buy these, do they?

Maybe your wannabe hip teen in his/her Nova/Saxo building their own amp?

they are also used in Inductance welding and heat treatment,  I.E.  a halfshaft is heat treated by passing a coil along the shaft

Favourite trick when I was an apprentice. Wire up these sort of things under someones bench, and do just that with remote wires  Grin Wink

Yes they are used - in more things than you'd realise. I know some high tech EMP devices use high rating caps though I'm not sure they're that high...
I wouldn't bother shorting one though! I once saw a small cap (10uF if I remember right) get shorted... the thing blew enough smoke we could smell it several feet away.
I need a new signature... i'm bored of the old one!
