Several scouts are walking together when one calls out, "Look,
tracks!" as he points down. They all stop and look down.
"Those are bear tracks!" calls out one. "No, those are wolf
tracks," says the other. "No, no - you guys don't know anything!
Those are tiger tracks!" Suddenly, a line of scouts holding each
other's shoulders come racing toward them from the other direction,
making chugga chugga train sounds while one makes a train whistle sound.
The "train" runs straight at them and knocks them over.
