Deniece Sims was the wife of Star Trek: The Next Generation property master Alan Sims. She portrayed a Bringloidi colonist in the second season episode "Up The Long Ladder". Sims was at this time pregnant and the script asked for a pregnant Bringloidi woman who was carrying a little African pygmy goat which was also brought by Sims to the set. Alan Sims talked about this in the TNG Season 2 DVD special feature "Departmental Briefing Year Two: Production" in the sub-special "Props".
