Because the front row are classed as specialist positions the IRB when it was agreed to allow reserves opted to number the hooker as 16 props as 17 - 18 . This allowed the officials to clearly see that these were player specific roles and if these players were in place contested scummaging could go ahead. If not and any of the front row positions not filled by "qualified" scummagers then uncontested scums have to take place.
The number is normally associated with the players playing position

Its not hook. Its hooker. The position is front row between the 2 props. Main role is to use their feet to hook the ball back when the scrumhalf places it in the scrum, (thats where the name hooker comes from) - In union the hooker also throws the ball into the line out.
number ten on the Irish Rugby team is Jonathen Sexton

no this has never happened
As part of the "pack" The eight forwards in union and 6 in league the hooker binds on (catches around) the prop forwards either side of them and in a scrummage their role is to "hook" back the ball as it is placed in the tunnel by the scrumhalf - This is where the term hooker comes from. IN the line out in Union only, the hooker will be given a call code by the lineout co-ordinator, normally a second row. The call is a code to where to throw the ball so that a jumper can catch the ball and gain advantage. In Rugby league the hooker acts as the "dummy player" Their role is to take a ball from the footback (a play where the tackled ball carrier places the ball to their feet and roles the ball back to the hooker) The ball then is passed in to play.
