I literally ate one spear of asparagus at dinner, and had asparagus pee. I have had this conversation with my friends and it seems that some people get this and some people have no clue what I am talking about. So, to cure my curiosity, lets do a poll:
Do you get asparagus pee? (poll results)
Every time I eat it 10 (76%)
Nope, not me 3 (23%)
I don't know what that is 0 (0%)
Interesting... And very scientific.
