You look around the room, and see absolutely nothing around you but space. You look back, and are relieved to see the portal you arrived through still there. You are just about to leave, when suddenly an old man appears, and notices you.

"I got a good feeling!" He says cheerfully, while seemingly hopping around on one foot in a circle. You stare at him, but he seems oblivious to your presence. After he completes 3 circles, a portal suddenly opens inside the circle.

"This is the way!" He says, as he jumps into the portal, which then disappears. You ponder this, knowing that you have to make a decision...

Do you Hop around on one foot in a circle three times to activate a portal and jump inside?

Or do you take the non-idiotic-looking way, and jump back in the portal whence you came from?
