An androgynous toilet symbol has sent Twitter into a flurry, after users were unable to decide if the symbol was for men or women.
The image, posted by British TV presenter Susanna Reid, shows a semicircle head on a longer semicircle body with two legs sticking out the bottom.
She risked the 50-50 odds, and immediately regretted her decision.
"I went in. I was wrong," she wrote.
However, a little bit of further investigation revealed the truth.
