This is not a bad episode and is quite different than all others. People change places through some scientific mumbo jumbo shenanigans, but it's a cute episode. I very much liked how the alien behaved in the end and the conversation he had with Daniel Jackson. There are some objectionable choices and behaviors to make the episode fit into 45 minutes, but it's not that bad. I am always pleasantly surprised by how unique and fun each SG-1 episode is.
