Merry Christmas, Nerds! Here’s some Christmas fungus on a petri dish.

Let it grow, let it grow, let it grow

Single cells, single cells,
See how they divide!
There was one on Christmas Day
But now they’ve multiplied

Single cells, single cells,
Nothing much to do!
But sit around in a petri dish
Dividing into two!
