Fundamentalists evangelists wear many different hats — not the least of which is the position of showman and entertainer. Most evangelists have some kind of hook, and act that is their signature. Ventriloquism, art, magic shows, karate (but the good kind not the evil eastern mysticism kind) demonstrations are par for the course. Many evangelists also sing and play instruments.
Now while some speakers will stick with guitar, piano, or trumpet others get a bit more…creative. You’ve never lived until you’ve been serenaded for 15 minutes by an accordion or heard How Great Thou Art scraped out on a muscial saw. But the prize for uniqueness goes to those few (including evangelist Hal Webb) who have mastered the art of playing the theremin.
For those of you who have never had the privilege of seeing one of these in action, the theremin is an instrument that has two antennas that adjust volume and pitch based on how far or close the players hands are to the antennas. So the evangelist literally moves his hands through the air in front of the instrument to produce the music. It’s the sort of thing that would have had you burned at the stake during the middle ages but makes for a great performance during special services.

Once a year, fundamentalists pack their kids a suitcase and wave goodbye as the youngsters are hauled away to Christian camp. This is considered vital to to the children’s spiritual upbringing and also gives mom and dad a break — defined as “only taking care of the four youngest kids.” It’s a win-win. 
A good fundamentalist is in church every time the doors are open, no matter how often that may be. (Hint: it’s often). 
Nothing is more bizarre to the outside observer of fundamentalism than seeing two fundies who have almost come to blows because each believes that the other is not a “true fundamentalist.” In fact, it’s every bit as fascinating as watching two Trekkies argue over the design of an anti-matter drive. Not only is it impossible to win such a fight but it wouldn’t really matter even if you did.
