T-Rex: Here are some things that are sad!
T-Rex: Abandoned puppies, and little birds with a wing in a cast. Aww!
T-Rex: And then you throw in an orphan with a crutch! And a little girl holding the limp string and rubbery plastic remains of her only birthday gift this year, a balloon with the words "Happy Birthday, Naseem!" printed on it. The girl's name is Jenn.
Dromiceiomimus: And the balloon wasn't filled with helium! It was filled with water.
T-Rex: Brackish, swampy water! And it was tossed to her without warning and now she's drenched.
Utahraptor: And the water also drenched the orphan and puppies and birds!
T-Rex: Yes!
Utahraptor: They're all drenched, lost in sorrow - a new kind of sorrow, a grief, a sadness so intense it could smother them. Dripping wet, staring at the ground, they weep. Eventually Jenn looks up and smiles as best she can, bravely, but it's so small, so fragile. She turns and walks away, her broken balloon dragging behind her.
T-Rex: A scientist runs up, explaining that dogs and birds can't cry! But, as she examines the animals she discovers that in addition to tear ducts, they have ALSO evolved the ability to experience sadness with an intensity previously unknown on the planet. THE END.
