A Queensland schoolteacher is creating quite a buzz after a video of his radical roll call idea was uploaded to Facebook.
Thomas Hams from Brisbane's Wellers Hill State School has a secret handshake for just about every student in his year four class.
Each greeting seems to have its own unique choreography and some even have animal sounds or words.
It is believed the idea came out of the US and Mr Hams thought it was an activity that could bring his class closer together.
It seems like it would be difficult to remember them all, but the teacher and his students seem to have the moves down pat.
Dozens of Facebook users have complimented the teacher's memory online.
One wrote: "Awesome work Mr Hams! Gosh knows how on earth you remember each special handshake. But Im (sic) sure the fact that you do, makes each student feel extra special each time you greet them!"
Another said: "That teacher needs a hi five (sic)"
While another wrote: "Absolutely brilliant, love it!! What a cool teacher and class of kids."
The video was posted to the school's Facebook page on Thursday and has been viewed close to 50,000 times.
"One of the most important things we do as teachers is to build relationships,” the post read, “and rapport with students and a great time to establish that is when students move into class. Here is the way 4H do it!!!"
