There's also the obligitory "we got stuck in a VR machine"--which I guess is kind of like the weather one you did, but oh well.

And this one was on SG-1, so it's not really a fanfic cliche, but just think how hard it would be for Brendon or Frank to convince *anyone* that it's not their imaginary friend, there really *is* someone there, you just can't see him/her. Honest.

Also, I want to know more about Iero the xenobiologist and his baby seals.
