When TIME went to interview astrophysicist and famous science communicator Neil deGrasse Tyson, they noticed a huge crate that had been shipped to his office.
Tyson had no idea what was in it, but agreed to open it on camera. His reaction is a pure delight to watch:
I love people who have such a capacity for enthusiasm and are not afraid to show it.
When was the last time something at work made you this excited?
