Barking mad owners have proved they really do look like their pets – by performing impressions of their own dogs. In a series of hilarious “paw”-traits, owners pull their best faces to look like their pooches. Snapped by photographer Ines Opifanti, people stuck their tongues out, yawned and tilted their heads in curiosity at the camera. Opifanti, from Hamburg, Germany, came up with the idea while interacting with her own dogs, two pug/French bulldog crossbreeds. Here: Amina and Zazou the dog. (Photo by Ines Opifanti/Caters News)

The orchestra is the brainchild of its conductor Favio Chavez, who wanted to help the children of garbage pickers at the local landfill, and the instruments are made from salvaged materials by craftsman Gomez. The orchestra now involves 30 schoolchildren who have toured countries in Latin America, North America and Europe to play music ranging from Beethoven and Mozart to the Beatles and Paraguayan folk songs.

The best man in a wedding party, who all declined to be identified, stands near the bride and groom as he holds an AR-10 rifle he was handed while the party was having their pre-wedding portraits taken on the steps of the capitol before a rally nearby by gun-rights advocates to protest a new expanded gun background check law in Washington state Saturday, December 13, 2014, in Olympia, Wash. The wedding party was not part of the protest, but posed for pictures with it after being handed it by gun activist Brandon Lyons, who said “we've all just broken the law”, by handing the gun over. Saturday's protest was called the “I Will Not Comply” rally, and those attending said they will openly exchange firearms in opposition to the state's new voter-approved universal background check law, Initiative 594. The law, which took effect on December 4, requires background checks on all sales and transfers, including private transactions and many loans and gifts. (Photo by Elaine Thompson/AP Photo)
