Ezra: I know! We can make the scarecrows' heads out of lemon oil.
Me: Lemon oil?
Ezra: Yeah, lemon oil!
Me: How do you know what lemon oil is?
Ezra: Duh, you let me and Jude play with it!
Me: What? I don't remember that.
Ezra: You know, we made boats with it and stuff!
Me: ....ooohhh, aluminum foil.
