Little did this school know that the Twitterverse would immediately fall in love with this story.

Twitter user @elle91 shared, a now viral, photo of one of her school's yearbook entries. The photo was of Miss Peanut, her school's therapy dog.

It didn't take long for most of Twitter to share their therapy dogs in their yearbooks. And it's 'Most Adorable. I totally agree with M DeMarco (@ireallyshouldbe) below:

USA Today has all the photos.
