With asparagus it must be a metabolite.  I wouldn't eat the stuff if it
smelled like that!
And while we're on metabolism, plant products, and human waste, (geez, we
must be biologists to do this!) I have some evidence that betalains are not
broken down in our bodies (at least not in mine).  I recall one time I tried
to expose my kids to beets.  I bought a fresh bunch, cooked them up, and
everyone refused more than the requisite bite.  My wife was no help
either....Anyways, I ate all of them in one sitting (yummy) and for the next
two days, ...well...everything was very pretty pink.

Willy, does that beat your coffee pee question for self-consciousness?  I
sure hope my students don't read this stuff.
