Some teachers reckon they can tell whether you're going to be naughty or nice by just looking at your name.
They've been chatting on a teachers' website about how they look at their register and try to work out what type of behaviour goes with which name.
Some teachers say Jordan, Bobbi-Jo, Ryan and Kristopher spell trouble.
But they reckon kids called Kate, Imran, Daniel and Lucy are generally well-behaved. One teacher reckoned he was 75% right with his guesses.
But some names appeared on both lists, proving that teachers have different experiences with kids who have the same name.
Some parents are annoyed by what the teachers have been doing, saying it's not fair to judge kids before you have met them.
