Go on, we dare you. Have a go at saying these impossible tongue twisters out loud. Better still, ask a friend to!
To sit in solemn silence in a dull dark dock
In a pestilential prison with a life long lock
Awaiting the sensation of a short sharp shock
From a cheap and chippy chopper on a big black block.
(by W.S. Gilbert of Gilbert and Sullivan from The Mikado)
