Demi Lovato's favorite dish is "a mug"

During an interview, Demi was asked "What's your favorite dish?"

She replied:

"I like mugs, because they're very comfortable in your hand. They hold hot things that you don't have to touch like coffee or hot tea."

She said she was joking. Ok I get it, because you put mugs on the "dish washer". She must be really joking. Because there is no way anyone would mistaken a mug for a dish. I would say that was just a terrible joke.
