Got this from my old high school Yahoo Group. You may have seen it before. Reeks of scenes out of the Beverly Hilbillies movie and is not the best parody of christian self-delusion ever put out there, but is amusing nonetheless.

"The other day I went to the local religious book store,
where I saw a HONK IF YOU LOVE JESUS bumper sticker. I bought it
and put it on the back bumper of my car, and I'm really glad I
did. What an uplifting experience followed.
I was stopped at the light at a busy intersection, just lost in
thought about the lord, and didn't notice that the light had changed.
That bumper sticker really worked! I found lots of people who love
Jesus.
Why, the guy behind me started to honk like crazy. He must REALLY
love the lord because pretty soon, he leaned out his window and
yelled, "Jesus Christ!!" as loud as he could. It was like a
football game with him shouting, "GO JESUS CHRIST,GO!!!"
Everyone else started honking, too, so I leaned out my window and
waved and smiled to all of those loving people. There must have
been a guy from Florida back there because I could hear him
yelling something about a sunny beach, and saw him waving in a
funny way with only his middle finger stuck up in the air.

I asked my two kids what that meant. They kind of squirmed,
looked at each other, giggled and told me that it was the
Hawaiian good luck sign. So, I leaned out the window and gave him
the good luck sign back. Several cars behind, a very nice black
man stepped out of his car and yelled something. I couldn't hear
him very well, but it sounded like, "Mother trucker," or
"Mother's from there." Maybe he was from Florida, too. He must
really love the lord. A couple of the people were so caught up in
the joy of the moment that they got out of their cars and were
walking toward me. I bet they wanted to pray, but just then I
noticed that the light had changed, and stepped on the gas. And a
good thing I did, because I was the only driver to get across the
intersection. I looked back at them standing there.

I leaned way out the window, gave them a big smile and held up the
Hawaiian good luck sign, as I drove away. Praise the Lord for such
wonderful folks."
