Jeopardy and Trains

[~Z~]

Watching Jeopardy tonight, and I beat the three day champion on this one question:

"For smooth travel, ballast tampers & ballast regulators keep the gravel at the right level along these."

The champion says, "What are roads?" Wrong....

Scary lady with braces says, "What are shoulders?" Wrong....

Third guy just shrugs his shoulders.

BEEP BEEP

Alex: "Along railroad tracks...... all the stones, all the rocks"

OWNED!!!
