By the time I get this response ready, this thread will probably be well past this point....but oh, well.
You're going by one definition of biomass. However, a form of wheat bread that "would" be biomass is old, moldy bread - no longer suitable for consumption. That said, cattails and weeds are also not considered "animal feedstock". However, a neighbor here feeds such to his cows regularly, any time his supply of the-cheapest-hay-he-can-find runs out. Therefore, it's difficult to accurately define an animal feedstock.
Both bread and many cereals, though intentioned for consumptive purposes, may also substitute as biomass. It sounds a little insane because it brings to mind someone going to the store, buying up fresh bread and cereal, then using it in this way. That's ludicrous, UNLESS you happen to be attempting an experiment and that is the most logical/convenient route to go.
Whether a joke or intentional, the same or similar ingredients apply, so who are we to say it DOESN'T work?!?!? Personally, I think it was quite clever!
In "my" opinion (not that it matters), Clay's posts are suitable. Maybe it would work; maybe it wouldn't. Maybe it was meant as a joke; maybe it wasn't. The one thing I do very much wish is, if someone is going to make a joke, to please make it an obvious one - like using the

and

emoticons, as well as making it verbally clear.
My 2 bits. ...Let's see, with inflation - oil prices - current political affairs....no, no - keep mistresses out of it! Ok, ok...this is my 1.367 bits worth!
