A pastor went into the pulpit one Sunday morning wearing a pair of new bifocals. The reading portion of the glasses improved his vision considerably, but whenever he looked through the top portion of the glasses he got dizzy. He explained to the congregation that the new glasses were causing problems, then said, "I hope you will excuse my continually removing my glasses. You see when I look down I can see fine, but when I look at you, it makes me sick." (from George McCracken in http://www.sermonfodder.com)
