I like
this cartoon . Galileo didn't actually drop stuff off the tower in Pisa, but it makes a good story! He did show that objects of different weights fall at the same rate.
So if I dropped my laptop (which keeps crashing & won't recognise my CD-ROM backups) AND at the same time dropped my netbook (whose trackpad whizzes the cursor all around and won't connect to the wifi), they should hit the ground at the same time.
Ok, where's the nearest tower?
