Isn't it funny how...
If you have a bunch of keys to try in a lock, the correct one is always the last one you try!
The stapler only ever runs out of staples when you are using it!
The fish were always biting "last week"!
You always sink the 4th [or 5th] putt!
Golf carts/buggies always break down at the furtherest point on the course from the clubhouse.
