My younger brother used to think that condoms were something like trading cards you show to your friends (courtesy of a TV show where the boy asked his dad for one and implied that it was so he could show it off). This led him to take one from my older brother's house and show it off to his friends in front of my dad. My dad took it away and then about a week or two later my younger brother saw a commercial on MTV about Fight for your Rights where the guy is trying to get a condom from the vending thingie and it won't give him one even after he's kicked it and stuff then there's a message like "No condom, no sex" or something and thats about when little brother caught on.
