Lily: See this, Anya?  It's a magic coin.
Anya: No it's not, it's a top.
Lily: No.  It's a magic coin!
Anya: Nuh ah, Lily.  It's just a top.
Lily: No, see this here?  It says, "G-A-B-H-O-M-A" which spells "Magic Coin!"
Anya: NO! It says, "H-I-B".  "TOP!"

Hey, what do you want?  They're only two and four.  We'll get them spelling in another six months or so, I'm sure.
