Reminds me of an episode of The Simpsons where they go astray on an Airforce base after a Airshow - MPs search for them in the Hangars, open the door to "Hangar 18" and a little alien lurking in a corner turns around and waves a green wand at them - one of the MP's shouts "Look out, he's got his probe!".

Just the suggestion that there's been other incidents when the unwary have wandered in there cracks me up.

It's just such a weird part of the whole UFO mythos...maybe they're intergalactic Vets and they're just taking the abductee's temperature the way we would a pet dog?
