Amanda Seyfried loves rude jokes

Amanda Seyfried finds penis jokes hilarious.

The 'Red Riding Hood' actress admits she has a "sick" sense of humour and is rarely shocked by rude gags.

She said: "I think it comes from the morbid sense of humour my sister has. I love sick jokes. I can't tell you, but what I will say is that nothing shocks me. Really nothing. Gross things make me laugh like a 12-year-old. Penis jokes make me laugh."

However, Amanda admits she hasn't always been so flippant and easygoing about sex and rude jokes because she had quite a conservative childhood.

The 25-year-old blonde told Marie Claire magazine: "Sex was meant to be a scary thing. Because of AIDS and pregnancy, we were constantly taught to stay away from it. Schools, videos, abstinence . It was just made out to be this very scary thing. My parents aren't very religious anyway, so that wasn't part of it. I think it was just the society where I grew up which made me look at it wrong. Also there were a lot of girls who got pregnant at school so that was terrifying."
