Not only is it a really fun book about a psychic ghostbuster named Felix Castor by Mike Carey, but it sorta applies to situations in everyday life. I looked up the origins on the phrase and they are as such:
"Better the devil you know than the devil you don't know - It is better to deal with something bad you know than with something new you don't; the new thing might be even worse. The proverb is of Irish origin and has been traced back to the 1539 Collection of proverbs by R. Taverner. First attested in the United States in 'Dodd Cases'(1934) by K. Livingston..." "Random House Dictionary of Popular Proverbs and Sayings" (1996) by Gregory Y. Titelman (Random House, New York, 1996).
I found this on http://www.phrases.org.uk a pretty entertaining site.
I really like the sound of the phrase and it does have a bit of good advice, but if you followed it you'd never try new things and move forward in life. You'd become complacent with your burnt toes thinking that dancing with another partner would be worse. You might even convince yourself that your devil isn't so bad, but wouldn't that be rather like stockholm syndrome?
So... maybe if you do swap you fiendish partner, you might still get burn toes, but you could learn a new dance :P
