Non-Words

In a series of experiments, it was found that the greater the ‘violation of the expected outcome’ the greater the humor feels. It also found that certain non-words, which are a combination of letter strings (like digifin, or artorts) but have no dictionary meaning, are the most consistent in their funniness rating.

Non-words with low entropy(the extent of them being unexpected) seem to offer more surprise, and therefore, get a higher humor rating.
