I cannot believe we'd ever doubt forty cents 'cause we were merely freshmen.

The story:

My little brother had his own version of this line, and as we were heated debating the subject my older sister pulled out the lyrics. She made us both look like morons. My line made sense to me because you know, they didn't think that it would be worth paying forty cents to buy a condom so the girl got pregnant. After all, they were only stupid freshmen.
