My wife and I were in Paris and tried to report a mallard duck with a bum leg to the front office as we left The Garden of Plants (rough translation). Because of our limited language skills, they came to believe we had brought our green and purple dog with us and lost it in the park. We eventually got it straightened out, but much hilarity on both sides resulted. I think we were obnoxious tourists laughing on the subway the whole ride home. That green and purple dog wanders yet in the parks of Paris.
