Dongle communism

If you have a mac and give talks or teach, chances are you have embarrassed yourself by forgetting your dongle. Our lab meetings and classes were constantly delayed due to missing dongles. Communism solved this problem. We bought 10 dongles, sprinkled them around the department, and declared all dongles public property. All dongles, not just the 10. No longer do we have to ask to borrow dongles because they have no owner. Please join the revolution. ps -I think this should apply to pens too!
