Caveman Tech Support

The tech support problem dates back to long before the industrial revolution, when primitive tribesmen beat out a rhythm on drums to communicate:

Grog: This fire help. Me Grog
Lorto: Me Lorto. Help. Fire not work.
Grog: You have flint and stone?
Lorto: Ugh.
Grog: You hit them together?
Lorto: Ugh.
Grog: What happen?
Lorto: Fire not work.
Grog: (sigh) Make spark?
Lorto: No spark, no fire, me confused. Fire work yesterday.
Grog: *sigh* You change rock?
Lorto: I change nothing.
Grog: You sure?
Lorto: Me sure. No change.
Grog: You sure?
Lorto: Me make one change. Stone hot so me soak in stream so stone not burn Lorto hand. Small change, shouldn’t keep Lorto from make fire, right?
