I first noticed this past tense of the verb hang on yahoo.com:
It piqued my curiosity: Were those mistakes in the actual article? Turns out they were. Here’s an excerpt of the article on Yahoo! Sports:
According to the American Heritage Dictionary, the correct past tense in this context is hanged:
Hanged, as a past tense and a past participle of hang, is used in the sense of “to put to death by hanging,” as in Frontier courts hanged many a prisoner after a summary trial. In our 2008 survey, some 71 percent of the Usage Panel objected to hung used in this sense. The Panel’s opposition to this usage has remained strong since balloting began in the 1960s. In all other senses, hung is the preferred form as past tense and past participle, as in I hung my child’s picture above my desk.
