We appear to have a programming strategy at my employer which could be termed the Pearl Fallacy.
Basically, the principle is that if you shovel enough shit into the codebase, it will eventually turn into a pearl. This only works for oysters.
It's more likely to turn into a gyppo (as defined by Terry Pratchett in Mort, IIRC - this post alludes to the meaning) - a solid looking crust on the outside, but absolutely disgusting if you put your foot through it.
(If you think I'm getting frustrated with my employer, you would be right.)
