I learned long ago to check my language at the door when it comes to cursing, and having grown up in the hey day of Warner Brother Cartoons, I always (thanks to EYEGORE) prefer to use Cartoon style expletives like this:
Suffering saccotash!
Heavens to murgatroy, etc . . . you get the idea.
Or as Bob Dylan would say:
MCMF is your temple, keep it beautiful and clean!
