One day Bob and Bubba went fishing. They were catching a lot of fish so they wanted to figure out how to remember this part if the lake.©JOKEDEMO.COM

Bob said, ''I know. I can spit in the water!''©JOKEDEMO.COM

But Bubba said, '' No! How will we know it's your spit?''©JOKEDEMO.COM

They thought and thought and finally Bob said, '' I know. We can draw an 'X' right here on the side of the boat!''©JOKEDEMO.COM

But Bubba said ''No, no, Bob. That won't work! How will we know that we get the same boat next time?''
