This poem saw its first incarnation on Twitter, the best place in which to write the short and sweet. But it’s now gone through several phases as it lingers in the twilight of my brain:
Poem of the Day #2:
Hemoglobin is red,
Western blot bands are grey,
my data is SWEET,
perhaps I’ll graduate someday.

Or Alternatively
My DNA polymerase is red,
My western blot bands are blue,
hire me as your post-doc,
my work will totally woo you.
