Yup - Mom, Dad, Brother, and me. I think we would probably go with my mom for the backstroke, me for the breaststroke, my brother for the fly, and my dad as the free. My parents could both pull off the free and the backstroke, but maybe not the others. My breaststroke is stronger than my brother's so that would probably be the best lineup. It would be fun to actually do this someday, if we're geographically compatible.
