Hogger, interesting. Reminds me of movie out now, a prequel to Charlton Heston movie late in his career "Planet of the Apes". (I never saw the original). Alzheimer's researcher trying to help his father ends up testing the serum on chimps - [and the rest is "history" (in Hollywood)]. The movie was pretty good. The end is rather like the last episode of Howdy Doody which I saw in about 1960 in that both Clarabel and the Chimp.... Don't want to kill it.
