1# Cucumbers are great friends. They are very loyal.
2# They are dumb. Now I know this sounds more like a con more than a pro, but think about it. Even if you have an IQ of a peanut, you will always be the smarter friend because cucumbers have absolutely no brains- you can always act like you're a genius or something.
3# If you are ever starving or dying of hunger, well great news- you have a friend who's is a cucumber! It won't hurt them if you eat them. They'll just rebirth as a new cucumber.
The end. Part 2 coming soon.
