Who has bad teeth and can't tell right from left? MY GYM TEACHER!

Allow me to set the scene. A class of twelve 15-16 year olds are sat in the center circle of their high school gymnasium after the floors have been smoothed and polished for the upcoming basketball season. A large, cranky, old woman with a mouth full of rotten teeth and a heart that only softens when it comes to boys' varsity sports, looms over the students. She hands them each a blank piece of lined paper.

She instructs them to write their names on the top line.

Each student writes his or her name on the top left of the paper on the line.

She then tells them to write the date in the top right corner of the paper.

Each student writes the date in the corner opposite their name.

And then,

Without warning,

ALL HELL BREAKS LOOSE.

She begins to scream at the students,

'ARE YOU KIDDING ME RIGHT NOW?!?! YOU ARE ALL SOPHOMORES IN HIGH SCHOOL!! YOU WROTE THE DATE ON THE LEFT!!!'

We politely and calmly tried to tell her she was wrong, but she wouldn't listen. She screamed and screamed, her face growing more and more red with frustration.

Realizing the stupidity of the argument was too great for any of them to handle, the students 'fixed' their papers and spent the rest of class mocking her loudly.

'HEY, WHAT SIDE IF THE GYM ARE YOU ON?' 'WHICH WAY DO I TURN?' 'AM I RIGHT HANDED OR LEFT HANDED??' 'HOW DO I DIRECTION...' 'IM CONFUSED ARE WE ON THE EAST OR THE WEST COAST?' 'DOES THIS MEAN DOWN IS UP??'

-
Yeah. High school. Sometimes it's the students who are dumb, sometimes it's the teachers.

Deep question for tonight,

What's the difference between right and left?
