Tell Us How You Really Feel, Rabbi
Rabbi Levy is having difficulty delivering his usual shabbos sermon. His new bifocals are making him feel extremely dizzy and he keeps on pausing to remove them only to put them on again a few seconds later.
After five minutes of doing this, he pauses again, looks up from his notes, stares at his congregation, and says to them, "I really must apologize for reading my sermon this morning and for continually removing my glasses. Some of you might have noticed that I'm wearing new glasses and these allow me to see my notes very clearly. But every time I look up at you, I feel absolutely sick."
