Monty Python's Flying Circus, Series 2

Mr. Wiggin:
This is a 12-story block combining classical neo-Georgian features with the efficiency of modern techniques. The tenants arrive here and are carried along the corridor on a conveyor belt in extreme comfort, past murals depicting Mediterranean scenes, towards the rotating knives. The last twenty feet of the corridor are heavily soundproofed. The blood pours down these chutes and the mangled flesh slurps into these...

Client 1:
Excuse me.

Mr. Wiggin:
Yes?

Client 1:
Did you say 'knives'?

Mr. Wiggin:
Rotating knives, yes.

Client 2:
Do I take it that you are proposing to slaughter our tenants?

Mr. Wiggin:
...Does that not fit in with your plans?

Client 1:
Not really. We asked for a simple block of flats.
