Well, I don't know if this is what you mean by "colorful" but we did have this one guy in the congregation. He was always very strange. He was a single, older man that liked to "trap" the younger girls (I mean like 12 - 15 year olds) in a corner to talk to them. I always thought that was strange and if I had known then what I know now I would have been much more concerned about it. I even think the elders had a couple of talks with him about it.
I say he was colorful because he was so different. He rode his bike everywhere. I had a part time job at a convenience store and the girls I worked with kept telling me about the "duck" man. They called him that because he would go into the store bathroom and when he would come out there would be water all over the place, floor, toilet, sink......it was as if he took a bath in there. Once I saw who it was I was so embarassed....I never admitted he went to "church" (the only term they would have understood) with me.
So, yup....I say he was our colorful character.
