In like a LION...
Out like a LAMB!
You have heard the old saying, "In like a LION and out like a LAMB." This actually has little to do with the weather and more to do with astronomy. Its origins lie with the constellations Leo, the Lion, and Aries, the ram or lamb. At the beginning of March Leo holds a prominent position in the sky and by the end of March Aries has taken his place. It's funny how things evolve with time.
