"Fast food chain Jack in the Box can continue to air TV ads that make a rival restaurant the butt of its jokes, a federal judge ruled this week. U.S. District Judge Andrew Guilford said he wanted to see more evidence of actual harm before barring the cheeky ads that suggest rival company CKE Restaurants, which operates Carl's Jr. and Hardee's, uses cow anuses to make its Angus beef hamburgers.
CKE sued Jack In The Box in May over two TV ads, including one in which executives laugh hysterically at the word "Angus" and another where the chain's clownish mascot Jack is asked to point to a diagram of a cow and show where Angus meat comes from. "I'd rather not," Jack replies. The employee asking the question traces a circle in the air with his pen while pronouncing the word Angus.

Maybe "Angus" might become a popular term of abuse now that it has been ruled legit!
