On the escalators from Longworth to Rayburn, one enterprising intern attempted to save time by transporting a large speaker between the two buildings via escalator. Part way down the first escalator, he promptly dropped the speaker and it slid to the bottom where it became stuck, blocking the exit for all those behind it. Our hero was left walking up the down escalator trying to push the speaker through the narrow escalator exit. Fortunately Capitol Police rescued the poor intern.
Lesson: next time take the freight elevator, that’s why it’s there.
