There's chasing your child around the house with a spider. Then there's this. 

Remember that scene from Bad Teacher where Cameron Diaz washes her car? Allow this Vine to jog your memory...then tear it to shreds.

Put your finger on the screen. (Seriously. Do it.)

OUR EYES! That's our hope of sleeping tonight ruined anyway.

We showed you this yesterday, but it's so jaw-droppingly brilliant we think it's worth a second (and third, fourth and fifth) watch. Remember: all of what you are about to see was done using only a smartphone.
