A group of unknown students at Minnesota’s Carleton College decided to PWN their very own Goodsell Observatory by dressing it up to look like a very familiar astrometric droid from Star Wars.

The epic pranksters decorated the observatory with pre-fabricated drapes and taped them around the building to look like R2-D2. 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.

Smart! 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.
