What is a tiger rock?

[cdelsolar]

Simpsons reference. A rock that keeps tigers away. “You don’t see any tigers around here do you?”

And here is a clip of the relevant scene, from the episode "Much Apu About Nothing" (1996), https://www.youtube.com/watch?v=xSVqLHghLpw

Quoting from its IMDB entry at https://www.imdb.com/title/tt0774432/characters/nm0810379 :

Lisa : Dad, what if I were to tell you that this rock keeps away tigers.

Homer : Uh-huh, and how does it work?

Lisa : It doesn't work. It's just a stupid rock.

Homer : I see.

Lisa : But you don't see any tigers around, do you?

Homer : Lisa, I'd like to buy your rock.
