"Caveman Tech Support" joke

The tech support problem dates back to long before the industrial revolution, when primitive tribesmen beat out a rhythm on drums to communicate:
This fire help. Me Groog
Me Lorto. Help. Fire not work.
You have flint and stone?
Ugh
You hit them together?
Ugh
What happen?
Fire not work
(sigh) Make spark?
No spark, no fire, me confused. Fire work yesterday.
*sigh* You change rock?
I change nothing
You sure?
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?
