How safe is it to have a monkey as a house pet?

Dib runs off to the warehouse duplicate Dib told him to go to—tripping over garbage cans and scaring cats along the way. When he arrives at the warehouse, he hears Zim's laughter echoing. He climbs in a window and finds the warehouse empty. On his video watch, duplicate Dib starts laughing. The laughter blends with the laughter coming from the warehouse and it's clear they're both Zim. Four boxes suddenly pop open and Zim's robotic lawn gnomes jump out and quickly incapacitate Dib. They throw him into a metal cage hanging from a cable as an Irken floating video monitor flies out from behind a stack of boxes with Zim onscreen. He gloats and explains that duplicate Dib is a remote-controlled robot he's used to trick Dib into this trap. And that he can have robot Dib sabotage PEG while he's safe in his spaceship in orbit. Just as Zim says goodbye, Dib hears Gaz's voice coming from the watch. She's telling robot Dib to come on (and threatening him if he messes things up). Dib calls out to Gaz through the watch but the robot's hand covers it, making it impossible for Gaz to hear him.
