Just a casual observation from a dad who has seen his fair share of vomit from all ages and both genders (and everything in between): Why is everything you throw up orange, no matter what color it was when it went down?
If aliens were to determine what we eat based solely on what we regurgitate, they would say humans diet consists entirely of badly processed carrots.
I have an idea for a new business: Vomit Stain. If you are feeling poorly, take a Vomit Stain to ensure a more appealing shade of puke. Anyone want to invest?
