That's clever; nobody suspects the guy buying bananas. They're high in potassium, after all! Plus, a banana will never get tired, or have a headache, or be "not in the mood right now," or ask you why you're spending so much time in front of the computer, or run off with a co-worker 10 years her junior, or demand a divorce...
I think you're really onto something here. F*ck Bananas, indeed.
One could probably fuck a banana every single day for less than thirty dollars per month. This idea will give Tinder a run for it's money so they better start looking into finding more fruits.
