Abby never met a holiday she didn't love, and encouraged others to do the same.

Let's face it, if Abby can find her holiday spirit while working in a lab where she is frequently investigating death and destruction, then the rest of us can certainly create our on sense of joy.

Not only does Abby Scuito love animals, but the biological brother she never knew she had works at an animal shelter.

The first time the two meet, he hands her a puppy. You can't get more perfect that that.

Actress Pauley Perrette may be an even bigger animal lover than her onscreen counterpart. She's lent her time and name to many animal charities over the years.

Here she shows off her three adorable rescue dogs while encouraging others to check out their local animal shelters to give a forever home to a new best friend.

On NCIS, we've seen Abby and Gibbs communicate using sign language, to the surprise of some of their colleagues.

Abby Sciuto's parents are deaf, and she is proficient in sign language, but we've never been told how Gibbs learned the language, although some fans theorize that military snipers are often taught a simple version of sign language in order to communicate nonverbally when necessary.

No matter how it began, fans have been fascinated by this language for several seasons, spurring some to learn it themselves, and spawning many a website post trying to translate exactly what the characters are saying to one another.

The list of people Abby Sciuto has been unkind to is downright miniscule.

Yes, there may have been some moments of jealousy on occasion, but if Abby shows her displeasure with someone it is usually because she feels they haven't treated her friends well. And no one messes with Abby's friends without her having something to say about it.

Abby not only has her own organ donor card, but she was willing to give one of her kidneys to a complete stranger. Maybe it shouldn't be a shock that, unbeknownst to Abby, her brother was willing to do the same.

An estimated 20 people die each day awaiting an organ transplant. NCIS used its TV bullhorn to draw attention to their plight, and Abby was the obvious character to be willing to donate an organ to help someone else, and encourage others to have the courage to do the same.
