Take Totally Looks Like, add some simple algebra, and you’ve got Facemath: the new facial recognition craze that’s traversing the Web.

For those of us without Prosopagnosia (that’s “facial blindness” for those of you without Wikipedia access), Facemath does unbelievable things with the nose-eyes-mouth area and will convince you that basically everyone is related.

While launched in May, the Tumblr has seen a recent spike in activity, posting a total of 14 visual mash-ups, which have received hundreds of thousands of likes and reblogs.

Here are some of the site's best (and worst) celebrity equations .

Add a dash of that guy from Whose Line Is It Anyway?, a squeeze of A-Lister Matt Damon and you get someone I literally cannot identify. But does it really matter? Look at that brow!

A drip of obscure brunette, a half-gallon of Justin Long’s gorgeous smile and you get Portlandia’s Carrie Brownstein. Spot on.

I think this is my favorite, as I’ve been personally trying to identify Waka Flocka Flame’s lookalike for weeks now. Alas, it’s Kel Mitchell (of Kenan & Kel) mixed with a rotund Charles Barkley (and a head of dreads, natch.)

Yeesh, let’s not even go into detail here.

Blond + adorable baby from Dinosaurs = Another, more famous, blond.
