User blog comment:JoePlay/Portal 2 Giveaway/@comment-3552081-20110416095527

I'd play real life portal with it! When travelling by plane, put the cube under me at the security gates, step on it, hop over the gates, and find out a way to return the cube. (Since you only get the cube, not the portal gun) I just hope I'll never have to destroy it or leave it behind just to finish a real life level(like getting married)...
