The Olan Mills "fake office" backdrop on in the first one is priceless. The "fake school" in the second "pull my finger" one isn't as funny, but Pat Robertson would probably want to ban the equations on the chalkboard as being offensive to God. And the last one is great, especially for the caption:
[It] contains three things radical liberals despise: the Holy Bible, an American proudly waving the flag and, of course, Dean Flickinger.
"Dean", of course, being a totally made-up title for this credential-less bozo.
