Kali of the Dance.
This video of a baby performing a traditional Irish-style dance routine is definitely very cute, but I'm 75 percent sure there's some digital fakery that went into it:
Notice how at the 3 second mark you start seeing some very quick edits, and then at 6 seconds you start seeing some split screen effects. Don't feel bad if you were fooled. These kinds of things go right past the untrained eye.
This is actually the exact same kind of trickery they use to make that Michael Flatley guy look like he can dance.
