Astronomy vs. Astrology?

[Professor Coldheart!]

I know the difference. One is complete crap I don't understand and the other is a science I don't really understand, either. But I need a mnemonic device (as opposed to a pneumonic device- ha!) to keep them straight. Anyone know a good one?
silly gooses. I mean the actual words. I always forget which word is which. It's a fairly common predicament, I suspect.
Thank you, madam passenger, that is exactly the sort of thing I'm talking about - and quite humorous too!
No, no! That's a really good one for five seconds of thought - Look Out! Garbage! Yes! That's pretty creative!

Astronomy has to do with plants and what goes on with them. Astrology has to do with the plants that deals with your future. Degree of the planets. It's kinda like divination. Celestial placements can aid in the interpretation of past and present events and in the prediction of the future. Of course people will doubt it.
