Story
Two boys are playing with their racing cars. Then they have a game of ping-pong. Later they watch a very strong man lifting weights, on television. The man grunts and groans, as he lifts, the heavy weights. The boys pretend to be weightlifters, too. They use a mop and a broom as weights, and grunt loudly, saying /ng/!
Song
If you're strong and you know it, say / ng/!
If you're strong and you know it, say / ng/!
If you're strong and you know it and you really want to show it,
If you're strong and you know it, say / ng/!
