School kids give first lady sarcastic "thanks" for unappealing school lunches on Twitter

WASHINGTON - School kids are giving thanks to first lady Michelle Obama just in time for the holiday — with a sarcastic Twitter hashtag about unappealing school lunches.

Along with photos of unsavoury-looking school meals, the hashtag #ThanksMichelleObama was among the top trends on Twitter within the United States for a stretch on Friday.

The first lady has become the symbol of healthier school lunches as she has pushed for standards implemented in 2012 that require more fruits, vegetables and whole grains in the lunch line.

Many of the photos have a Thanksgiving theme while others are everyday meals. One of the most retweeted photos was from 17-year-old Hunter Whitney of Wisconsin, who posted a photo of a soupy Spanish rice gone wrong and an apple on his tray.
