The autotrophs began to drool

OK, Big Bang Theory, I was wrong to condemn you for the autotrophs reference.

Mea culpa, but you culpa, too.  Your reference made no sense without explanation.

Note: In the comments that follow there is an unusually enjoyable discussion referrence to "chemoheterotrophs did in fact exist before chemoautotrophs"

Well, I found it enjoyable.
