A group of University of Washington college students made their own Star Wars costumes for a Halloween party in 1977 and staged a skit at the party. Andrew Siguenza was R2-D2, and the highlight of your day is his Flickr album of the party and costume prep.
Every time I think I’m too tired to go on with the blog, I find something like this.
2 Warps to Neptune 
Best R2D2 ever!
That R2D2 doesn’t look all that different from the one my dad made for me for Halloween of 1977.
I hope they returned that trash receptacle to the local bank after the party was over.
