Truckin For Jesus

So here's a pickup I saw on the highway today.It's hard to read (hey a cell phone at 75mph at 3x zoom).

On the left it says Hugo Chavez Kiss My American Ass. Okay pretty much my sentiment.

On the right, Iran President Kiss My Christian Ass. Well I think Ahmadinejad is a jerk and dangeroud but I'm not religious.

But just what does Joe Christian not get?
