While searching for my next Jap school to attend, I came across two of the worst Romanizations of Cantonese and Hokkien shop names ever:
A tire shop called Kum Ho Tires.
A hawker centre called Bee Fatt.
And just for fun, here's an extract from the Devil's Dictionary:
Gold, n. A yellow metal greatly prized for its convenience in the various kinds of robbery known as trade. The word was formerly spelt 'God' - the l was inserted to distinguish it from the name of another and inferior deity.
Edit: Since we're on the subject of gold, kindly take a good look at this article before your next investment in a shiny trinket.
