"No, you don't understand sheep"

Sometimes I slave over a hot keyboard for an entire weekend to get a point across. With elegant arguments, carefully constructed logic, and a full path from beginning to end. Integrated across 3 separate disciplines. If I get to QED in less than 3 pages, I'm happy!

And then Gunnar comes along and says:

A teacher asks the class, 'If there are nine sheep in the pen and one jumps out, how many are left?'

A little girl says, 'None of them are left.'

The teacher shakes her head sadly and says, 'You don't understand arithmetic.'

The girls says, 'No, you don't understand sheep.'
