Does Bribery Ever Work

I was thinking this morning while I giving Cambree a bath, how can I avoid a total meltdown while washing her hair. I have tried using a bribe and that didn't really go over to well. I think one time I offered her jelly beans if we could wash our hair without crying, screaming, etc. It started ok, for a few seconds of course, and than all the screaming kicked in. When we got out of the bathtub she looked at me and said, "Jelly Beans." Of course holding firm to my agreement I said no, you don't get any jelly beans because you cried while I washing your hair. Of course she only heard the no part, and not my reason and proceeded to now cry and scream about that. So today as I am washing her hair, she started her usual protest, I didn't say anything. I got her out and she looked at me and said, "Jelly Beans." I thought oh great here we go again....I don't even currently have jelly beans in the house right now. This bribe I'm referring to, only occured one time, I realized real fast it wasn't going to work, so for her to ask again was interesting to me.
