This episode is a self parody of a slight quirk
Thomas Sanders has when doing real life shows, that can also be seen in bloopers when doing fiction stuff. He tends to look at himself in the camera screen, check if his hair is all right and fix it with his hands if it's not (and sometimes even if it is). He's said he does this because his hair naturally goes to the front in the middle of the forehead, and he has to pull it back with his hands all the time.
