Small children and Kanye West can agree on one thing: Beyoncé's "Single Ladies (Put a Ring on It)" is one of the best music videos of all time. New Zealand tot Cory Elliot's diaper-clad bob to Beyoncé has been seen by nearly 5 million people since January and set off waves of infant (and adult) imitations. What makes Beyoncé's video magic? "Young children love songs with good rhythm and repetition, and 'Single Ladies' certainly has both," Kara Shall, communications director of Baby Loves Disco, told TIME in October. But father Chester said Cory might simply like dancing: he has released videos of Cory getting down to "Ghostbusters" and the theme song to the cartoon show Avatar.
