This is a whole different kind of Parent Trap (though, if Lindsay Lohan is still looking for work, we wouldn't mind seeing this viral video adapted into a feature film. She can be an extra or something).
This little baby met her dad's twin for the first time and it blew her mind. Understandably so. Because twins are as insanely weird and confusing to babies as seeing a clone would be to a fully grown adult. But the reaction is cuter when it's a little baby.
