I LOVE these! I don't really eat butter, but I do eat corn, and if I had one of these, then I'd be lathering up the butter all day. They can be bought from the wishing fish, and apparently you put half a stick of butter (!) in the top, press the plunger down and it applies a layer of butterery and cholesterol induced yumminess on to your corn. .
I'm sorry, I know these are completely supurflous (because how hard is it to put butter on corn really?) but their little faces are just so cute, I couldn't resist!
