Biography
At the Bedrock Adoption Agency, he and his wife, Mrs. Henderson, received a baby of their own from Mrs. Pyrite.

He was later seen at work at Slate and Co., a day or so later, where he was on his lunch break. At this point, Cliff Vandercave, the executive vice president, informed the workers that they would be participating in an aptitude test for a possible promotion. Mr. Henderson had raised his arm, but Cliff said that questions would come after.

At the aptitude test, he sat next to Joe Rockhead, who tried looking at Mr. Henderson's answers.
