Cave Man 1: “I got an idea: let’s sharpen some long sticks and try to poke and kill a mammoth? Whose with me?”
Cave Man 2: “ Yeah right...”
Cave Man 1: “I got an idea: let’s dig a huge pit on the mammoth trail and put long, sharp sticks at the bottom. We’ll cover it with branches and leaves, and see if we can stampede a mammoth into it.
Cave Man 2: “I’ll help dig, but you can do the stampeding.”
Cave Man 1: “Hold muh beer.”
