I’m surprised this is not bigger than it is: the device that lets every woman be a man. Better known as the Whiz:
“Its unique shape was tested by over 1,400 women in clinical trials and since then by thousands of women of all ages, from all walks of life. When held properly the Whiz Plus will not leak and stays completely dry on the outside.”
I’m particularly impressed by the accompanying advice, which a few of my male friends could stand to be reminded of:
When outside aim downwards, keep your back to the crowd and never ever pee into the wind!
Oh, and put the seat down after.
