We're not in Kansas anymore...or Sunnydale either!

Buffy references to "The Wizard of Oz":

1.06 The Pack - Buffy refers to the hyena-possessed bullies (not including Xander) as "the winged monkeys"

1.10 Nightmares - The Scoobies are around young Billy Palmer's hospital bed when he awakens from his coma. He looks at them and says, "I had the strangest dream. And you were in it....and you..."

2.10 What's My Line (Part 2) - Xander says, "Welcome my little pretties" as the bug man (in buggy form) falls into Xander and Cordelia's trap.

4.20 The Yoko Factor - Willow says, "If ever a wiz there was" as she and Tara defend her computer skills to Spike.

5.05 No Place Like Home - see title of episode

6.22 Grave - Willow sends a ball of fire after Xander and Dawn with the instruction, "Fly my pretty. Fly!"

7.19 Empty Places - Rona states, "Ding, dong, the witch is dead" after what I refer to as the "mutiny scene" where Buffy is asked to leave the house.

And of course there's Seth Green's character of Daniel Osbourne...better known as Oz.

Season three was the only season in which I did not see a specific reference and I can't help but feel like I missed something. Please let me know if I have!
