The line comes from Disney's 1992 animated film Aladdin, where the Genie explains his magic after being freed from the lamp. Voiced by Robin Williams, he boasts about his phenomenal cosmic power before shrinking his voice for the punchline about his itty bitty living space. The boast alone became a quotable shorthand online, clipped for reaction videos and edits about superpowers, overpowered game characters and anyone acting far more powerful than their situation allows. Its contrast between grandeur and limitation keeps it instantly recognisable decades later.
