"I sort of noticed there were no urinals," said the teenager. "But I had to go to the bathroom so bad because I got a refill on that large Coke, and I couldn't go back out and find the men's room."
As the teen was in the stall, he said he heard "women's voices." It was then that the reality hit him that he was, indeed, in the women's restroom.
"I saw him go in the girls' bathroom," laughed his younger brother, Wesley, who immediately summoned his father.
They both were waiting with a camera and took this picture of Calvin exiting the women's bathroom.
When asked why he didn't leave the women's restroom once he realized he was there, he said he had already began to urinate.
"I was midstream, and I couldn't, like, just stop. You know."
