from Wikipedia:

'Several American TV shows have used this surname. The sitcom Married... with Children featured a character whose maiden name was Wanker, who was from a fictitious Wanker county in Wisconsin.

An episode of the U.S. comedy Mork & Mindy featured a character called Oliver Wanker and led to severe editing when the commercial network ITV originally broadcast it in Britain; when the more liberal Channel Four rebroadcast it some years later, it was aired unedited.'

this has made my day, dunno about you. oh wait there's more:

There is a community in Oregon called Wanker's Corner; here, Wanker is believed to be the surname of a saloonkeeper who founded an eponymous establishment there in the early 20th century
