In 1985, while Too Close For Comfort was being retooled as The Ted Knight Show, Bullock learned that he was HIV positive. In a 1985 appearance on the game show Body Language, host Tom Kennedy described him as looking "like you're in the pink of health and all of that", to which a flustered Bullock responded "I'm, I'm...no, I'm about to die, actually. But let's not talk about that now, OK? Fabulous." Kennedy then remarked that "If you've got about four days left in you, we'll make it till Thursday", and Bullock replied "I've got four days, yeah."
