US actors Jennifer Aniston (L) and Owen Wilson taste dog food after loosing a bet during the German television show 'Wetten dass...? (Bet that...?)', in Duesseldorf, Germany, 28 February 2009.

And Owen, you have to eat one. Jennifer, you can eat it if you want, but I'd really like to be able to tell my grandkids that I ate dog biscuits with Jennifer Aniston."The trio eventually tucked in, with Jennifer commenting: "They're a little dry."Owen appeared to enjoy his, prompting Thomas to give him a handful to enjoy later.
