They have teeth, people

But seriously, ya they are aggressive, but unless your a small child, you are easily ten times the size of that thing, those "teeth" aren't all that dangerous. They act tough because it can scare most animals, even if they are larger. If anything doesn't run away and advances towards em back, they get scared themselves.

Clearly you haven't had any real dealings with geese. They will attack adults, my mom has marks to prove it, and those teeth hurt like hell!

As one who actually raises geese, I say that grabbing them by the neck and giving them a quick shake is all that's needed. Sure they'll still hiss and charge but then you turn around to them and those fuckers back off.

See Lucifer, I told you to control your kids.

Boo

No offense but penguins are cute geese are just hell spawn assholes!
