Good Tidings from Jolly Ol' St Nickase!

Here are some good tidings for the season!

I SAW THREE SNPS

I saw three SNPs come sequenced in
On CRISPR day, on CRISPR day
Yes all three SNPs came sequenced in
On CRISPR day in the morning
On CRISPR day in the morning

And what was with those SNPs all three
On CRISPR day, on CRISPR day?
And what was with those SNPs all three
On CRISPR day in the morning?
On CRISPR day in the morning

The TracrRNAs were there
On CRISPR day, on CRISPR day
The Spacers and Repeats were there
On CRISPR day in the morning

And HDR the changes made
On CRISPR day, on CRISPR day
Oh, with all the target changes made!
On CRISPR day in the morning

Then let all the lab rejoice again
On CRISPR day, on CRISPR day
Then let all the lab rejoice again
On CRISPR day in the morning!

GOOD NEWS,  YE MERRY GENTLEMEN

Good news, ye merry gentlemen,

Now nothing you’ll dismay,

Remember that our Savior

Was born on CRISPR-day

To save poor souls from Mutant’s power,

Which long had gone awry.

And it is tidings of comfort and joy.

In genes that were our father's

The blessed changes came

Unto some certain Cas9 kit,

With tidings of the same;

That he was born in perfect health

The Son-of-CRISPR, named.   

Oh! tidings of comfort and joy, etc.
