Next time they have a group over for Bible study, drop in for a visit. Jump up on a table and start singing "my nutsack brings all the girls to the yard." If they start to pray for you, loudly declare they should pray with their inside voices. Or you could simply tell one of their female friends, "oh, I can make you scream out God's name". Pause for lightning bolt. Whew! No lightning bolt, looks like I'm safe. Best solution, be an absolute dick and make their life hell. They know you have a problem and refuse to compromise, I say give 'em a taste of "do unto others as you would have then do unto you." Smite them mightily. Declare a jihad. Issue a fatwah, though a fatwad to one of their eyes would be more entertaining. Time to nut up or shut the fawk up. If you're not even going to try, then end the story now dammit. If you can't stand up to a couple of noisy girls, I question your testicular fortitude. Swing your sack like a man.
