Be careful with those things! I hear that they are *very* dangerous. Archimedes says that with a big enough one, he can shift the Earth around. I'm very afraid of accidentally sending our planet hurtling off down the wrong path in orbit!

Imagine being ***that*** guy: 
"Why is it so unseasonally cold Mary?", 
"Well Jane it's because some moron called 'A Bit Brainless' disrupted our orbit while making dinner last Tuesday", 
"Oh really? What a prize wombat this fellow must be!". 

It would be *most* embarrassing!
