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

 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. Only small change, shouldn't keep Lorto from make fire.

 *Groog grabs club and goes to Lorto's cave*

 *WHAM*WHAM*WHAM*WHAM*
