´╗┐Fast clips show hands typing into a laptop keyboard, swiping on a smartphone screen, reaching for pickles inside a jar, touching elevator buttons, shaking other hands and grabbing snacks from a bowl.

LAURA says PLEASE, FOR THE LOVE OF HUMANITY, WASH YOUR HANDS.

(fun music plays)

As clips show dirty hands barely touching running water, then rubbing against a pair of jeans, Laura says NOT LIKE THIS. OR THIS.

As a dog licks the hands, Laura says OR EVEN THIS. TO DO IT RIGHT, YOU HAVE TO DO IT LIKE THIS: WET YOUR HANDS FIRST.

As a hand pours milk over another hand, Laura says WITH WATER. WELL DONE! NOW, SOAP.

As the hands get covered in ketchup, Laura says TRY AGAIN, THAT'S FOR SURE KETCHUP.

The hands rinse, apply soap and start to rub against each other creating foam.

Laura says THERE WE GO, NOW RUB YOUR HANDS PALM TO PALM. FRONT TO BACK, INTERLOCKING. PALM TO PALM, INTERLOCKING. NOW CLASP AND RUB ON BOTH SIDES. KEEP GOING, THOSE HANDS ARE STILL SUPER NASTY. UH-UH-UH! DON'T FORGET THE THUMBS. NOW RUB YOUR FILTHY FINGERTIPS IN THE PALMS OF YOUR HANDS. FINISH OF WITH THE WRISTS, AND RINSE.

As the hands pour milk, Laura angrily says WITH WATER! DRY WITH PAPER TOWEL, AND THEN USE THE TOWEL TO SHUT OFF THE TAP. WHEN YOU'RE DONE WITH THE TOWEL, DON'T EAT IT!

A short clip shows Laura chewing on a paper towel, then throwing it out.

She continues
THROW IT OUT INSTEAD. OH, GOOD JOB! ALL THAT SHOULD TAKE YOU 20 SECONDS. JUST THINK, THAT'S ONLY TWO ROUNDS OF COUNTING TO 10, OR 10 ROUNDS OF COUNTING TO TWO.

As clips show Laura and Lucas sneezing, coughing and pretending to vomit, Laura says 20 ITTY-BITTY SECONDS THAT'LL PROBABLY SAVE YOU TWO COLDS A YEAR, A COUPLE ROUNDS OF NAUSEA, VOMITING, AND DIARRHEA. SO PRETTY PLEASE WITH SUGAR ON TOP, WASH YOUR DISGUSTING HANDS. AND NEVER, EVER, TOUCH YOUR FACE AGAIN, EVER!

As four hands touch Laura's face, she says OKAY, REALLY? AMAZING. SERIOUSLY? THAT'S DISGUSTING.
