Disclaimer: Unfortunately, Santa did not give me the rights to CSI this year, so (sigh) I must put in this disclaimer. Oh, I don't own "Rudolph the Red-Nosed Reindeer," either.

A/N: This idea was my own :P If you have one, leave it in a review, please!

The CSI Christmas Choir Presents:

Greggo the Spiked-Haired Lab Rat

You know Grissom and Sara and Warrick and Nicky,

Willows and Ecklie and Curtis and Jimmy,

But do you recall

The most famous lab tech of all?

x-X-x-X-x

Greggo, the spiked-haired lab rat

Had some very shiny gel.

And if you ever saw it,

You would even say "bloody hell!"

x-X-x-X-x

All of the other CSIs

Used to laugh and be so mean.

They never let poor Greggo

Come to process their crime scenes.

x-X-x-X-x

Then one foggy Christmas Eve

Grissom came to say:

"Greggo with your hair upright

Won't you go to the scene tonight?"

x-X-x-X-x

Then all the CSIs loved him

As they shouted out in glee,

Greggo the spiked-haired lab rat,

Soon you'll be a level three!
