Caution: Greenhorn on the runway...
As I taxied into the number two position (holding short of the runway behind one of the local flightschool aircraft) I switched to tower frequency -- just in time to hear the following transmission between the tower and student pilot:
Tower: Skyhawk 123 taxi into position and hold.
Skyhawk 123: Aaaah ...
Skyhawk 123: ... Assume the position, 123.
