Lisa Kudrow isn't ''adventurous'' like her 'Friends' character.

The 52-year-old star portrayed daring Phoebe Buffay in the TV show for its ten year run but has admitted she has no similarities to the character which propelled her fame. When asked by chat show host Conan O'Brien if she had done any ''fun or crazy'' activities over the last few months, she admitted she hadn't but that her husband Michel Stern and their 17-year-old son Julian had been on a tour of South America.

She said: ''They went to Peru, the Amazon, and the Galapagos Islands and Machu Picchu.''

When asked why she didn't go, she added: ''I can't ... I wouldn't be fun, my husband sends movies and pictures and I saw them on a bus on a narrow road with cliffs on either side, passing another bus, I can't ... I can't do that.

''It's a human being driving who could make a mistake, I can't.''

And when Conan told her, ''You're not the adventurous type. You won't get on a bus because a human being could be driving it,'' she replied: ''Not at all ... I don't trust robots or computers either.''
