My first year in college, I had a buddy on my dorm floor (9’th floor) nicknamed “Jack Daniels” who used to climb out his window and walk the 5-inch ledge over to neighboring windows in order to horse around with people. Didn’t matter if there was snow on the ledge... he did it all the time (well, mainly when drunk).
A friend in college climbed to the seventh floor and knocked on his brother’s window.
