Good one, Mark!
The initials on the mascot stand for "Toronto Regiment", right?
Dave, now RSM of the Royal Regiment of Canada, has nowhere near the amount of hair that is shown.
A nick name that we always used for him was "Yah, yah".
Whenever he could, he would interrupt anyone's conversation by saying..."Yah, yah, but while I was on my mortar course..."
Of course, don't we all have our idiocyncransies?
