Do you know of other interesting devices or circuits good for misuse?
Unbuffered logic gates can make a really bad but still useful analogue
amplifier by adding feedback and bias.
E.G the CMOS 4007. See the old handbooks for a '100dB
amplifier' based on a RCA chip - there was a wiring
error in that old description - IIRC it was 3800? -
whatever, the 4007 is the same chip.
