Date of birth: August 23rd, 1989.
Jethro was born in the laboratory but was never considered a good research subject. In his 8 years at the lab he participated in only 3 studies. "Ch-667" refused to eat or drink when he knew he was in a study. Yet, he was knocked down some 142 times and still had to undergo 3 punch liver biopsies before he was 7 years old. Most of the knockdowns were to keep his teeth clean. Jethro still shows signs of a tendency towards depression, and can still be found to slap himself and rock as he used to do in his 5x5x7' home.
