This is supposed to have happened in Santa Cruz, Bolivia. A lady went into a bus and told the bus driver to let her out at the sign that said "200".
Turns out she meant the zoo - the sign has letters, about 2 meters (2 yards) high, reading "ZOO".
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
