Our trusty ace-o-meter has the answer

During tournament play with a free BMW on the line

During a simulator round

After kicking off a tree, cart  or other solid object 

While playing a nine-hole par-3 course

While playing solo 

If you own the course

With a provisional Ball 

During a round cut short by weather/emergency 

During foursomes play, your tee shot

During foursomes play, your partner’s tee shot
