No, this isn't a dirty joke. I love banana hangers. I love bananas and I hate bruises; I thought the only way to avoid them is eating green bananas. I DON'T HAVE TO EAT GREEN BANANAS ANYMORE! This $3 tool is awesome and it is the perfect gift for someone you don't really want to buy for but have to.
I found it at Walmart for $3.
Below are options I found on Amazon for more. I don't recommend paying more, but these give you an idea of the variety available.
