Well, first of all, because they have a lot of sex, and that makes everyone happy. They can also lick their own pink bits. But male rabbits are particularly pleased and confident because if they were to get bobbited, they could regrow a new penis.

Researchers at Wake Forest Institute for Regenerative Medicine have discovered that fully functioning penile tissue can be regenerated by rabbits, much in the same way a salamander can grow a new tail.

This may be good news for men with erectile dysfunction and men who may have lost their penises or use of the member due to an injury, disease or insane wife.

The team had success in using cells from rabbits to grow replacement penile erectile tissue for the rabbits in the laboratory. After the tissue was implanted, the rabbits had completely normal sexual function and even fathered baby rabbits.

The same team of hero scientists who worked with the rabbit penises are well known for engineering human organs in the lab. They are responsible for the engineered bladders of about 30 children and adults.
