Just slip in some nonsense...
I have been known to put technology faults down to 'spimf on the defributator', sneak the word 'wibble' into particularly long, boring segments of documentation and alter my client's logo at a microscopic (pixel) level on documents to include miniature cock drawings.

How about using imaginary units of measurement? Like the 'glimbart', or the 'Malcolm' (for anyone who's seen that Dr. Who episode).

I've also gone over sentences I've just written, examined every word and tried to think of another similar word or words to replace it, providing the replacement word has more syllables. E.g.

"Today, I went to the shop and bought a pint of milk, a loaf of bread and six eggs."

becomes

"On Thursday the 4th of May, I travelled to the purveyor of groceries and purchased one pint of pasteurised cow product, 500 grams of reformed wheat and half-a-dozen unhatched chicken embryos"

Or you could try putting your sentence through Babelfish, translating it into Korean and back again, and using the translation. The above example becomes:

" Today, going to the shop, the milk and the loaf of bread and 6 eggs." Bought the [thu] which is a justice green onion;"

Marvellous fun.

Don't forget...
... to use alternative forms of the word.

A wibble (noun), wibblish (adjective), wibbled (verb) etc etc.

Let us know how it goes!
