Actress Liv Tyler was stunned by a recent trip to Mexico City when she learned a pal's story about drunks getting electrocuted was for real. The Lord Of The Rings star accompanied pal VICTORIA to her home city - just to discover if her stories about young boys hooking barflies up to car batteries to sober them up were honest. And she was amazed to find they were: "She had always told me this really funny story that I didn't believe, that was when you come out of a bar and you're really drunk there's these little boys that stand outside with car batteries and electrocute you; give you a shock to sober you up. "I never believed her... but she took me to this square... I think they think it works - to sober you up. It's so weird, it's crazy."
