Here's the answer, revealing that the original poster is of puerile mind and unserious mien:

"Mianus is one of many neighborhoods located within the Town of Greenwich, Connecticut.

The community is located in a river valley formed by the Mianus River. It is home to North Mianus School, an elementary school. The Mianus River is dammed at East Putnam Avenue. The dam separates the tidal salt water estuary from the fresh water river. The area above the dam is called Mianus Pond.

The area and the river are named after the chief of the Siwanoy Tribe of Native Americans that inhabited the area when Europeans first encountered them. The Siwanoys sold areas of what is now called "Old Greenwich" to the first English settlers of the town for "40 English Coates" in 1640.

Mianus was featured in a segment of the MTV show Jackass in which Johnny Knoxville made fun of the town's name by pronouncing it "my anus", for example "Do you sell a lot of chocolate milk in my anus?" and "Are there a lot of famous people in my anus?" The segment culminated by visiting the sewage treatment facility of Mianus."
