The second stage consists of the actual delivery of the puppies. The third stage is passing of the placenta. The afterbirth might pass with each individual puppy, usually within 15 minutes of delivery. If the mother has a few puppies in rapid succession, those placentas may come out en masse.
Comedies have also been classified in various subgenres, such as romantic comedy, crime/caper comedy, sports comedy, teen or coming-of-age comedy, social-class comedy, military comedy, fish-out-of-water comedy, and gross-out comedy.
Below I have compiled a 30 different comedy forms with my own descriptions, suggested year levels at which to study them in drama, plus links to relevant published articles on The Drama Teacher. Low Comedy requires little skill in the scripting (if there is a script at all). Often a visual or highly physical work. Appropriate for all year levels. Slapstick is knockabout, physical humour. Media examples include The Three Stooges, The Marx Bros, Laurel and Hardy and Mr Bean. Appropriate for all year levels.
