There's worse things t'be than a jerk
You Are a Total Jerk
Honestly, you really don't care what other people think of you. And it shows!
It's a dog eat dog world out there. And you're not about to be anyone's snack.
While there's no harm in looking out for yourself, your plan may be a little short sighted.
Someday you may need a favor from someone, and that favor will be hard to collect on if you've burned your bridges.
Are You a Jerk?
