It's amazing the number of things that are yellow in color that are unappealing. Lemonade is pretty great, but I wouldn't say it's a best thing in life. It's not even that yellow and it's liquid, so there's no chance of it looking like a banana. There might be a banana-shaped drink pitcher or beer mug, though. Closely related to lemonade, but produced in a completely different manner and lacking lemonade's appeal, is urine. Sure, you can pee into your radiator or write your name (poor penmanship included) in snow or even drink it if you are lost in a desert, but it's not considered a good drink. I doubt chilling it or adding sugar would improve the taste. Then again, some people go gaga over coffee beans that a cat shit out.
