Three friends were hiking through the forest when they stumbled upon a large pile of poo. Curious, they decided to examine it closer.
The first friend said, "I think it's bear poop, look at the size of it!"
The second friend disagreed, saying, "No way, it's definitely moose poop. You can tell by the texture."
The third friend, not wanting to be left out, bent down and took a closer look. After a few seconds, he stood up and confidently declared, "You guys are both wrong. This is clearly human poop."
The other two friends were shocked and asked how he could possibly know that.
The third friend replied, "Because I can see a newspaper sticking out of it with yesterday's date!"
