April Foolin'

I had this fantastic idea a couple of years ago, and no one would bite.

1. Say you are a lady, in a solid enough relationship that your man can take a joke.


2. Say you are not yourself pregnant, and that within the confines of said relationship, pregnancy is not being welcomed -- much less planned -- in any way, shape, or form.


3. Say also that you have a pregnant coworker, friend, etc.


4. Finally, let's say that you buy a pregnancy test, have the pregnant lady in your life take it, and then leave the test out in the bathroom at home that evening. It'd obviously have to be the kind where it is painfully obvious what the result is.

How is that not the best April Fool's joke ever? 

Also, if you are a woman in a relationship with another woman, does that make this prank funnier, or less funny?
