The church had an aging pastor. He got this new glasses with lined bifocals as the congregation would not afford no-line bifocal lenses for him.
The Sunday morning he came wearing this new pair of bifocals for the sermon. The lower reading portion of the glasses improved his reading, but the top portion of the glasses didn't work so well. In fact he was experiencing dizziness every time he looked through them or switched from lower reading lenses to upper distance lenses. Worried about his job, he apologized to the congregation and 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."
