Physicists isolate the fundamental building blocks that form the Cosmos we see around us. They then pass them on to chemists and biologists who will play with them for hours! (Old departmental insult from CalTech).
or,
If a biologist kills you, you die in writhing agony, probably infecting any that try to help you in your death-struggle; if a chemist kills you, the end comes quicker, but the building you are in may also cease to exist or you will be reduced to some ghastly, ichorous, dark liquid on the floor; if a physicist kills you, forensic scientists will spend years trying to decide why a perfectly fit and healthy person should drop dead in a bus queue...(not sure - Max Planck, I think).
And finally, from one of my own sixth-formers,
Physics is really very simple. You don't have to know much, but you have to understand a great deal...
The scientific hatchet is thus buried!

I wonder if Uranus has Hummers?
