Good morning. I'm David Greene with some truly laughable research. Facebook has published a report on how people these days are expressing laughter in posts and comments. The company looked specifically at haha, hehe, LOL and of course some kind of happy emoji. The winner haha is used most frequently, and that includes variations like hahaha.
