Long story short, Paul couldn't get Chiquito out of the escape area back into either half of the cage. Chiquito nibbled on Paul's ankle. Paul pushed him off. And then Paul yelled: "He bit me hard!" as blood pulsed out of his forearm.
There was blood everywhere. Oscar turned the hose on Chiquito, who headed into the cage. Oscar then proceeded to hose enough blood out of the escape area for a vampire film. In the meantime I called our neighbor Gloria to come up to monkeysit Lolita, wrapped Paul's forearm in a towel, and drove him into town to our doctora...who is also a surgeon.

"Were you playing or fighting?" she asked Paul.
"Fighting," Paul responded.
"Poor monkey!" she said, and laughed.
When Paul went back for his follow-up visit, she inquired about Chiquito and they both laughed.
