Most species of wild bathrobe are hermaphroditic. This can easily be checked for a given bathrobe: the cord is the male sexual organ, while the pocket or pockets are the female sexual organs. In the case of two-pocketed bathrobes, intercourse must take place with both pockets (with one end of the cord each) for pregnancy to occur.
The main division among bathrobes is between Bathrobes of Law and Bathrobes of Chaos. The former prefer to hang on coat hangers, which occur naturally in the forests where they dwell. The latter prefer to lie on the forest floor.
