The 39 steps

Thanks for that truly appalling joke... I feel that I must for a moment come out of retirement and offer one of my own...

Two young university students are writing notes in the library. Suddenly someone opens the door, and a gust of wind sends all their papers into the air. They retrieve some of them, but due to static, a fair portion stick to the wall next to the table. The students collect as many as they can, but the ones at the top of the wall are out of reach. They try standing on the table, but they still can't reach. Eventually, one of the students hits on the idea of throwing erasers to knock the papers down. The lower papers are knocked down quite easily, but only one of the students can consistently knock down the papers closest to the ceiling. The other student looks to the successful one and says "You must be a hell of a singer... you're hitting all the high notes..."
