Never try and teach a pig to sing

Never try and teach a pig to sing. It wastes your time and annoys the pig. - Source unknown

I got this way back in high school, reading over a mini-magazine with witticisms. My friend Tetay and I laughed our heads off while "reflecting" on the adage. Our classmates got curious why we were laughing and just pointed at the quote. We only received a handful of glares. Perhaps Tetay and I only know how to teach a pig to sing. :P

But kidding aside, I think there's a ring of truth in this witty remark. Don't you think so?
