This isn't a joke, I repeat, this is not a joke. The plane in Lake Harriet is not in the lake. It is invisible because of the satellite pic, so there's no plane in Lake Harriet.

Listen here, buddy. The 'joke' is that there's a plane in Lake Harriet that can't be seen on a satellite pic. So this dude is saying it's INVISIBLE. He's trying to be funny by saying it's not a joke when it's OBVIOUSLY a joke. And you thought that was funny? I bet you still get your mom to cut your sandwiches into triangles, don't you?
