text: This gives a whole new meaning to the phrase 'bouncing baby'. Angelina Santini from San Diego, California, filmed her nine-month-old son Marcus getting carried away in his bouncer one day. The comical clip shows the youngster lurching back and forth with the device almost touching the floor. 'Hi, are you having fun?' his mother asks at one point, to which Marcus replies with a loud squeal. He then stops to look at the camera before starting his bouncing stunt again. After a few gentle rocks, he's soon going at full speed with his arms waving in the air. Adding to the performance, he trills his lips at the same time. At the one-minute-30-second mark, Marcus shows no sign of slowing down. Four years on, videos show that the youngster has swapped his passion for bouncing with playing the guitar. With so much energy though, it's likely he'll be strumming some some rock n' roll beats instead of classical sounds.
