I'm not sure if it's been mentioned but if you right click the GIF and select open in new tab, it'll take you to the imgur page for it. But if you look closely, the phrase "It takes 2 twoo" is repeated behind the original, however, it may be a bit hard to see.
I'm not really sure what to make of it.
Edit: I found that zooming in between the default view and about 150% will show the repeated phrase.
