Science lesson “How to grow human livers on a mouse”

It just goes to show
what some scientists do
and who bloody funded it
the likes of YOU
we scrimp and we save
and they blow it all
proving that science
can be a fool

a mouse is a soul
with a heart and feels pain
human livers on mice
now what do we gain
from that pray tell me
what can we expect
them to be vectors
for organs
reject
the animal
testing the cruelty too
when we pickle our livers
on vodka
a new
one will be coming via Minnie or Mickey
to my mind this whole science
just got too tricky!
