Can you say banana joint?

So I just came up with one of the greatest weed smoking ideas of the decade. I legitamtely want to patent this because once this takes of it's going to spread like a California  Wildfire. (Literally it might cause as much smoke as one of those." It goes something like this, you know when you were younger and kids you know would smoke out of apples. It was the easiest way to smoke for someone that didn't own their device and didn't want to use an aluminum can. Well anyway what if you unpealed a banana and made a small tunnel going through it the long way (you could just do this using piece of wire or even a toothpick.Now fill this hollow section out and fill it up with the greenery. You now have a banana joint. Yeah I understand the fruit part wouldn't burn but you could line the tunnel with rolling papers or something so the good stuff stays lit. This is genius I know. What else could we use? Maybe perhaps a carrot, asparagus,  cucumbers you name it. And here's a kind of spinoff of this. You know how coconuts have hard outer shells with you have to puncture a hole in to drink the milk juice ( At least I think it's juice. Could be milk. Don't quote me on this) well you could definitely fill up one of those suckers with water and have a home day coconut bong. It's like fruit and weed were just meant to go together.
