Ismo Mikael Leikola, known professionally as ISMO, is a Finnish stand-up comedian, musician, author, screenwriter, and YouTuber. Leikola made his United States debut in 2014, when he was awarded the title of "The Funniest Person in the World" in a contest organized by the comedy club Laugh Factory.
Here he explains the subtleties of the meaning of "ass" when coupled with various other words to a Standard English speaking audience (i.e. proper English like what you and me speak.) His patience with the inadequacies and unoriginal lexicon of the average American-English-speaker borders on sainthood.
What a treasury of insights and clarity for anyone not born into the language of Shakespeare, Milton, Keats, Sir Laurence Olivier, the late linguistic genius Professor Stanley Unwin, and probably God.
