GRAND CANYON. BtVS Intertext/Allusion.

In "The Freshman" a reunited (after their post-graduation summer vacations) Buffy and Xander have the following conversation:

Buffy: What'd you do?  What'd you see?

Xander: Well...

Buffy: Tell me!

Xander: Grand Canyon!

Buffy: You saw the Grand Canyon!

Xander: Well, I saw the movie Grand Canyon, on cable.  Really lame.

Grand Canyon was a critically panned 1991 Lawrence Kasdan film about the interwoven lives of six modern-day Los Angeleans.
