Campbell also performed a routine with various partners generally known as "That's Bad/That's Good." Campbell would state a troublesome occurrence; when the partner would sympathize by saying, "Oh that's bad," Campbell would quickly counter, "No, that's good!", and then state a good result from the previous occurrence. When the partner would say, "Oh that's good!", Campbell would immediately counter with "No, that's bad!" and tell the new result, and so on.
