A blonde named Georgina went to the eye doctor to have her eyes checked for glasses. The doctor directed her to read lines of letters with the left eye while covering the right eye. Georgina was so mixed up on which eye was which that the eye doctor took a paper sack, cut out a single hole, put it on her head so it covered the appropriate eye, and asked her to read the letters again. As he did so, he noticed tears dripping from the bottom of the paper bag.
Look, said the doctor,
there's no need to get upset about needing glasses.
I know, she cried,
But I had my heart set on wire frames.
