LOL! This reminds me of an old friend, who created an elaborate female Ferengi costume for one of the cons up here (Norwescon? Sakuracon?). She was in one of the costume contests, and had the whole place howling with her strip tease act … IIRC, her chest was normal/human-like but there were definitely multiple butts!
(no silicone, though - her get up was a hand sewn and stuffed bodysuit)
