Some things I remember:

1) In April 2008, a French woman was sentenced to jail because she cut off her lover's penis and told the police the dog would have eaten it. Bad luck, she had drugged him before...neither weapon nor penis were found.

2) There are rumors about a thief putting a lobster (!) into his pants when leaving a shop. Afterwards, his testicles were gone.

3) During the 1990s there was a flasher in Germany whose penis was bitten off by a Bernese Mountain Dog. Same fate met a guy in St. Albans (UK).
