T-Rex: Bah! Nostalgia!

T-Rex: What use does it serve?

T-Rex: All it does is make us want things that we can't have, and can't even work towards having. Forget it! It's WASTED TIME.
T-Rex: From now on, I will not spend time remembering the past, nor will I be sad when circumstances change! From now on, I am all about TOMORROW.

Utahraptor: Are you sure that's a good attitude, T-Rex? Those who cannot remember the past are condemned to fulfill it!

T-Rex: And those who cannot remember to attribute their quotations are condemned to commit academic offences!
Utahraptor: It's common knowledge who said it! Sheesh! GEORGE SANTAYANA.

Narrator: HELPFUL ONE-PANEL SUMMARY:
T-Rex: Nostalgia can make you sad!
Off panel: Attribute carefully!
