When I was 8 or 9 there was a commercial for Powerpuff Girls cereal. After watching the commercial I thought the cereal would actually give me superpowers, so I begged my parents to buy me the cereal (I didn't tell them the reason) and my dad had to search all over the place for the cereal and when I finally got it I found out it did not give me superpowers, and it tasted horrible.
