A US woman was horrified to discover she'd let her young son wear a graphic sexual T-shirt to school.
Shelley McCullar, from Texas, posted a photo to Facebook of her son Anthony wearing a red shirt with a large yellow design on the front.

At first glance the image looks like the famous 'golden arches' logo of fast food chain McDonald's.
On closer inspection, however, the T-shirt is clearly designed to resemble a woman's open legs - lending quite a different meaning to the slogan 'I'm lovin' it', which is printed below.
Ms McCullar says she was extremely embarrassed when she realised the raunchy meaning behind the shirt, which Anthony had worn to his school, Travis Elementary.
She says she "would never let my kid wear something like this". The shirt was one of a number of hand-me-down clothes given to the family by a friend, and she hadn't yet had the chance to go through the items thoroughly.
In a video included in the post, Anthony says he was unaware of the shirt's true meaning but that none of his teachers noticed it either.
"They thought it was McDonald's too," he explained.
Ms McCullar says she was able to laugh through her embarrassment, but she'll take greater care in future.
"I promise from now on to monitor what my kids are wearing!"
