Students at Minnesota’s Carleton College decided to pull an epic joke, when they decided to dress up their observatory. The result was as epic and awesome. What people could see when the sun finally dawned was a gigantic R2-D2 incarnation standing where the old observatory previously was.
Just to be on the safe side, no spray paint was used for the prank so there was no serious or permanent damage to the property. On top of that, the decorations were accompanied by Artoo sound effects as well. No one has officially come forward and claimed the deed, but these prankster may have pulled off one of the greatest Star Wars pranks of all time.
