Instant Monkeys Online is a fictional online monkey dealership mentioned in experiment #822, Overdrawn at the Memory Bank. Crow and Servo order a monkey that they name Henry Kissinger and bring it aboard the Satellite of Love.
It is unclear precisely how the 'bots were able to access the internet, but apparently Crow has become more proficient with computers since experiment #612, The Starfighters.
The only known advertising for Instant Monkeys Online comes in the form of a jingle that The 'Bots sing:
"Get your monkeys instantly, at Instant Monkeys Online!"
