Pranks can be so vicious!

Apparently someone yarned a few of my intern friends cars together last night. While they were away for the night cleaning a church owned campground some terrible vicious people yarned their cars together. Who would do such a naughty thing? I have no clue but all I can say is the person that worked the blue yarn was pretty impressive. She, I mean, this person weaved the most intricate beautiful spider webs in and out of their cars.
I do not know who would do such a vicious thing to these hard working young men. Especially while they were out serving the church. All I can say is the pay back is going to be pretty intense. Eeeeekkk! *gulp*
