It isn't just babies and young children who can raise a smile (or a tummy-aching howl). These teenagers have proved a hit online with their antics, pranks, parties and moves and grooves.
Here, we take a look at the best viral videos starring teenagers. We have the lads trampolining into a swimming pool (and casually catching a flying basketball as they do), teachers turning the tables on lippy pupils, and a healthy dollop of ridiculous pranks that only your average 15-year-old could get away with.
Happy viewing!
