hahah.. you can freeze it and once all the last rotten bananas are saved in june you can make banana bread. i personally would throw it in a smoothie or make pancakes with it... but I always have a ton of bananas haha and there are always at least 5 bad. Also if you have house plants you can put the banana in some water for two days, let it soak and then water your plants with the water, then toss the remaining banana...I have a whole bucket of smelly bananas right now hahaha
