On his album "Cowboys and Colored People", Flip Wilson told a series of zoo stories. One was "
The Go-Rilla" (YouTube).
In another story, (embellished by me) a zoo patron bought some peanuts for the monkeys, but they were not out where they could be seen. Finding the zookeeper, he asked, "Where are the monkeys?"
The zookeeper said, "It's their mating season. They are in the back."
The zoo patron asked, "Won't they come out for peanuts?"
With a wry grin, the zookeeper asked, "Would you?"
