Not wanting to do the lame "Bible Themed" party, we had a 50's party, complete with a mirrored ball, a live 50's band and 50's dance lessons. The sisters bought or made vintage dresses and the guys greased their hair back and wore 50's cloths, leather jackets,etc. Some even brought their dates a corsage. When the Circuit Overseer came around we got counsled about it. He had heard about this one sister who came as Marylin Monroe (she looked awesome) and another brother came as Groucho Marx complete with a fake cigar. The Circuit Overseer said instead of imitating Hollwood Sex Goddesses and the like, we could have dressed up as Witnesses from the 50's and how they would have looked going from door to door. (No...I'm not kidding here) We just looked at him dumbfounded. You could tell as soon as he said it that he felt pretty lame, but he held his ground anyway.
The next time we played it safe and did a country and western party and had bluegrass music and hired a guy to call out the dance steps. There was a hay ride and bobbing for apples. It was fun but it felt like we were copping out a little.
