An entertaining enough episode, although I can see what the previous reviewer meant when he compared it to "some precious little community college production of an 'original' play". The set-up does have that air of pseudo-intellectual pretension about it which is hardly improved by the story's title.
Being originally from Glasgow myself, I also couldn't help groaning at the stereotypical portrayal of the Scotsman (and that accent is one that even James Doohan would've been ashamed of). To be fair, though, the plot does attempt to provide a a reason *why* each of the characters is something of a stereotype.
On another note, why did it take the prisoners so long to come up with the idea of the "human pyramid"? It occurred to me within a couple of minutes. They should also have allowed the piper to always support the bottom of the pyramid, in case he chose to wear his kilt in the traditional manner. xD
I have to admit that, ballerina aside, the cylinder does look like an awful place to spend eternity. It even has a clown in it (yes, I'm coulrophobic). I suspect that within a relatively short space of time I would've been tempted to discover if murder were possible within its confines. After all, in addition to being a clown, he was also irritating. :P
