Nice little joke ... Mice with balls

Secretary: "Pastor, we've got a problem in the computer lab where you met with the confirmation class last week. Some of the boys in the class started messing with the mice."
Pastor: "What?!?" (thinking: we've got mice in there!?)
Secretary: "Yeah, it seems some of the boys removed their balls."
Pastor (incredulously...): "Th..th...they did what??? How in the world did they do that???"
Secretary: "They must have used a screwdriver or something."
Pastor: "We've got some pretty sick boys... I... I... Didn't even realize mice had balls...!"
Secretary: "Yeah, they roll around on 'em all the time!"
Pastor: "What???" (still thinking of the little fury real animals) "Well...what can *we* do?"
Secretary: "I guess we'll have to put 'em back on the mice. I can probably do it if I can get enough little screws."
Pastor: "WHAT?!?"
Secretary: "Hmmm....Pastor, are we talking about the same thing?"
