Being caught in an act of Bestiality in Denmark. Strangely it isn't illegal there, so there's no legal problem, but when your friends and family find out...

'Tragic' car accidents involving all her pets.
First offences with small amounts of drugs will, I think, not get prison time, depending on the country in question.
