Ryan Walker said the image of the male organ was painted by members of his band during his bachelor party six months ago, but he and many of his neighbors did not find out about the phallic artwork until recently, the Arizona Republic reported Tuesday.
"I think it's hilarious," Walker said. "If you woke up and the news is at your house, and you had a giant penis on your roof what would you think?"
Neighbors said they were just as surprised as Walker to find out about the image.
"It was like a hit of coffee or something in the face," neighbor Darnell Whitfield said. "A penis on the roof. I was like,'Huh? Are you serious?'"
Walker said the story of the penis painting on his roof could be therapeutic for the United States.
"With the economy, with the Bear Stearns thing happening today why not a giant penis on the roof?" Walker asked.
