In Thai culture, two always packs more punch than one. After all, this is the home of the original Siamese twins. In the local language, words are often repeated for emphasis, and even when English is used, you often hear the "same same" words spoken twice. In the case of Bangkok taxis, it is common to see duplicate decorations on dashboards and in the back of cabs. I'm wondering if these cloned characters and twin talismans are supposed to bring double the luck, or did the cabbies simply pick them up at "Buy one, Get one" sales.
