If hagfish are caught by a predator, they can quickly release a large amount of slime to escape. When released in seawater, the slime expands to 10,000 times its original size in 0.4 seconds. If they remain captured, they can tie themselves in an overhand knot, and work their way from the head to the tail of the animal, scraping off the slime and freeing themselves from their captor. The hagfish’s mucus would clog the predator’s gills, disabling their ability to respire.

From Wikipedia:

Gropecunt Lane (/ˈɡroʊpkʌnt/) was a street name found in English towns and cities during the Middle Ages, believed to be a reference to the prostitution centred on those areas; it was normal practice for a medieval street name to reflect the street’s function or the economic activity taking place within it. Gropecunt, the earliest known use of which is in about 1230, appears to have been derived as a compound of the words grope and cunt. Streets with that name were often in the busiest parts of medieval towns and cities, and at least one appears to have been an important thoroughfare.

Although the name was once common throughout England, changes in attitude resulted in its replacement by more innocuous versions such as Grape Lane. A variation of Gropecunt was last recorded as a street name in 1561.
