They do look quite a bit alike. Not being racist or anything. But these two white boys could have come out of the same birth canal. One is fair haired, one is not, I know but their features are quite close. Regarding the sanity part: It’s all in the eyes. Scroll over their heads and take a look at what they were thinking the moment the photos were taken. Then you’ll see what I mean.
Ryan Gosling
Giovanni Ribisi
Told you so.
Nice Girl Mean Thoughts 
Ya, it’s just you.
nope everyone else should agree with you. Ryan gosling is not attractive and looks pretty nerdy. if you look at the picture of Ryan gosling with a beard and look at giovanni in ted and imagine him with a beard they look the same. Ryan gosling looks better in the picture you put in than he really is. Just as giovanni looks different now.
yes def
They are both great actors. Giovanni is a better actor, but Ryan has more appeal. They particularly used to look more related when Ryan was younger, like around the time of the movie Fracture. One could easily think they were full brothers back then.
