Nature of Time

Hello!!! My name is Waddle. I am a wise and precious mallard who is very old. I teach geography, science, natural disasters, history, and even French and German. I also teach waterfowl health and duck anatomy. Any strong swear words that I do not allow in comments will be censored by a bleep sound. 
The age ratings I use to rate my films:
G (General) - Suitable for all ages 
PG (Parental Guidance Suggested) - May not be suitable for 7 or younger 
PG-13 (Parents Strongly Cautioned) - Inappropriate for under 13 
R (Restricted) - Under 17 needs an adult 
NC-17 (No One 17 and Under Admitted)  - Suitable only for adults
