Early in the show, Howard confessed that he didn't know what was going on with his friend, Ralph.
Robin said she wasn't sure either: "He won't really talk about what's going on with him...every once in a while he'll slip and say something's got out of control."
Howard jokingly wondered if Ralph really might be gay. Howard then tried to figure out how old Ralph was--eventually Fred cut in: "He's allegedly 45."
Howard remembered Ralph's last girlfriend, a Middle Eastern girl with a heavy accent, and laughed that Ralph's apartment scared her. When she saw all his action figures and Pamela Anderson posters, she locked herself in the bathroom and called a friend.
