In studying the relationship between brain function and language, University of Alberta psychologist Chris Westbury found that people agree nearly unanimously as to the funniness of nonsense words. Some of the words predicted to be most humorous in his study:
howaymb, quingel, finglam, himumma, probble, proffin, prounds, prothly, dockles, compide, mervirs, throvic, betwerv
It seems that the less statistically likely a collection of letters is to form a real word in English, the funnier it strikes us. Why should that be? Possibly laughter signals to ourselves and others that we’ve recognized that something is amiss but that it’s not a danger to our safety.
