Am I the only one who thinks this sounds like a line/reference thing from David Tennant (The 10th Doctor) sang?

Like this verse: "We go together

Like two birds of a feather

We...

Fit like hand and Glove"

I mean, not exactly fitting but it sounds a lot like it. XDDD

Either way, I luffles this picture. The adorableness makes me squee.. XD
