Mother: “why are you home from school so early?” son: “i was the only one who could answer a question.” mother: “oh, really?
What was the question?” son: “who threw the eraser at the principal?”
Interesting Fact: Before rubber erasers, tablets of rubber or wax were used to erase lead or charcoal marks from paper. Bits of rough stone such as sandstone or pumice were used to remove small errors from parchment or papyrus documents written in ink. Crustless bread was used as an eraser in the past; a Meiji-era (1868-1912) Tokyo student said: “Bread erasers were used in place of rubber erasers, and so they would give them to us with no restriction on amount. So we thought nothing of taking these and eating a firm part to at least slightly satisfy our hunger.” ( https://en.wikipedia.org/wiki/Eraser#History )
