What Would You Do If You Had A Portal?

So if you had a portal, what would you do with it? Taking a look at smpfilms' take on it, I would probably do the same thing. Of course, it would depend where the portal leads. Is it a cool time portal, or just a simple distance portal. It looked like Mr Safety's portal was the latter as he seemed to reach into his refridgerator and put his cat on his stratching post. Don't really want to know where he was aiming in the second part of the video - probably his downstairs neighbor's apartment would be my guess.
