Me show you how to make peanut butter jelly sandwich.
You Needum: bread, peanut butter, jelly, plate.If you have no plate, you can use flat rock.
Get tribe to put bread on plate. They no listen to you, hit them with a rock. If you have no rock, you can use plate.
Open jars. Me reminded of joke, How many cavemen it take to open jar? That one crack me up.
Then put peanut butter on bread. Use knife for spreading. Sharp rock can be used if you lose knife when hunting yesterday's dinner.
No let caveman swim in peanut butter. Stinky Caveman. No soap invented for million years. 
Then put jelly on bread. Use knife for spreading. Sharp rock can be used if you lose knife when hunting yesterday's dinner. Me already say that. 
Sandwich done. Feed tribe for many moons. Make sure you hide sandwich from Thunder Lizard.
