As a kid, I would watch old classic cartoons every day after I got home from school (quite old ones). I was a rather big fan of Popeye. I saw that by eating spinach, he got big and strong, and I (despite being a girl) wanted to be big and strong like Popeye too. So I asked my parents to buy and cook some spinach.
Not only did it taste bland, but I was quite annoyed when no matter how much I ate, I didn't grow huge muscles. But if at first you don't succeed... well, I ended up trying again a few more nights, and finally gave up after no results. Dammit.
