One of his findings was that humor was (and probably still is) a critical part of building a successful relationship - so if you can't remember the last time you and your significant other made each other laugh like crazy, you might be in trouble.
In a statement, Hall explained: "People say they want a sense of humor in a mate, but that's a broad concept. That people think you are funny or you can make a joke out of anything is not strongly related to relationship satisfaction."
"What is strongly related to relationship satisfaction is the humor that couples create together."
You know, those in-jokes that you have with each other, that everyone else just thinks are weird?
"Say you and your partner share a quirky sense of humor, but romantic comedies or sit-coms do nothing for either of you... It's not that any style or a sense of humor is any better or worse.
"What matters is that you both see quirky humor as hysterical. If you share a sense of what's funny, it affirms you and affirms your relationship through laughter.
He went on to explain how making fun of each other is a big part of it:
"Playfulness between romantic partners is a crucial component in bonding and establishing relational security. Particularly shared laughter, is an important indicator of romantic attraction between potential mates."
But then again, you can go too far with the banter, as Hall explains:
"Having an aggressive sense of humor is a bad sign for the relationship in general, but it is worse if the style of humor is used in the relationship. If you think that your partner tells mean-spirited jokes, then it's likely you've seen that firsthand in your relationship."
So, there you have it folks - tease away, but the banter has to stop somewhere!
