Bocal care
Terry has the right answer: the main reason for putting the bocal in the bell is to protect the bocal. They are apt to catch on things like curtains, tuxes, etc., and bend, which leaves a crease that is impossible to remove. The bocal is never the same afterwards, and can't be restored to its original shape. Since they can cost several thousand $$, particularly for a "pre-war" Heckel, bassoonists take great care with them.
Hanging the bocal doesn't do much toward drying it out. The tip is small enough that moisture can collect there, but usually there is not enough to form a drop and fall out. The player just blows out the moisture (from the wide end), and this is sufficient to take care of 99% of the water.
The reed end of the bocal is tapered, so the "sharp" end is unlikely to contact the inside bore of the bell. You would have to deliberately gouge the inside of the bell in order to make a mark.
Enjoy!
