Extreme ironing is a sport in which people take an iron, an ironing board, and clothing to extreme locations, such as mountaintops or erupting volcanoes. Participants then proceed to neatly iron the items of clothing. Security camera footage in the UK caught one man ironing in the middle of a freeway. That section had been temporarily closed, so there wasn't much risk. Still, it's a good start, and the bathrobe was certainly an appropriate costume.
