FODEF 

FODEF is an amalgamation of the words 'Forkulate' and 'Deforkulate'. To 'Forkulate' is to turn an object of being into a fork, and to 'Deforkulate' is to do the opposite. FODEF is the name of the process in which these two are used together, and is commonly used in dishwasher-related time travel.

Have you tried FODEF yet? It's meant to be really, really good.
