Oh, forget the air horn.
Too easy to hide in the crowd and not be seen.
For maximum effect, bring your 6 foot long shofar and stand at the front during worship and blow it every minute during the worship music, especially if it's during the *free worship*.
And, hey, don't forget your flags so you can flag during the worship and nearly poke someone's eye out cause you weren't looking at what you were doing. Especially since you will be doing it with your eyes closed as you walk back and forth across the front to look even more spiritual.
And then if you are at least fifty pounds overweight, come to church dressed in a tank top and shorts and *dance* across the front of the church.
(I wish I were kidding. On all of them. Some things can't be unseen.)
And THIS is why whenever someone says ‘contemporary worship,’ I suffer a minor case of PTSD. I haven’t seen things QUITE as bad as all that using those words as an excuse, but it was bad enough!
