Say a giant penis is painted on the roof of a house during a bachelor party, and no one ever sees it. Does it really exist? 

Some neighbors say "enh" and others are disturbed by the giant "male sex organ" friends painted on the roof of an Arizona man's house during his bachelor party six months ago. The home owner, Ryan Walker, didn't even know it was there until his local news station alerted him.

Neighbors on his street in north Phoenix also said they had no idea it was there, and were shocked to hear about it. "That was a little eye opener," said Darnell Whitfield. "It was like a hit of coffee or something in the face. A penis on the roof. I was like huh? Are you serious? 

The City of Phoenix said the issue would be taken up by the Neighborhood Services Department only if someone were to make a complaint. In that case they said they would handle it like graffiti and ask the homeowner to remove it. Walker said he will probably paint over it anyway, because he's a neighborly kind of guy.
