How do you spot a human/alien hybrid?

Check the eyes when the mouth smiles

The eyes will not be smiling.

Check the shape of the

eyes and the pupils.

You see a snake?

eyes
tongue

use your spidey senses.

DNA

Smell. It's real subtle.

Put the glasses on!!

^^this too

lift her skirt if the fold runs from anus towards the belly button then she is an earthling if that fold runs perpendicular then she is an alien hybrid.

..... wait I think I got that sort of backwards it's Asian women that have the sideways fold. idk really I've never had any yellow meat before maybe I should have left this question for someone else

you don't spot them.... they spot you..........

they have pimples on their butts

otherwise- totally indistinguishable

good luck

"wait I think I got that sort of backwards it's Asian women that have the sideways fold."

incorrect- dock that man 2 days weekend leave- report to my office.

see if they have a dick or puss, then smell it, if it smells like space then they are an alien

oh wait, you've never smelled space? then wait for the sexual harassment/embarrassment suit......

Reading their energy signature would be the best way of knowing.

Blood type rh neg

If you see red hair, run. They are possessed.

If this where to be the case, i would say reading their aura would be the best bet (feeling their vibe). Higher beings tend to radiate energy outwards with great force, human or not.
Or im sure their DNA would be different, but i dont think docs would now how to spot the difference yet.

Good luck accomplishing either of those :P

Look for the black suit, no tan, and out of date sunglasses.

Just look for the tail.

they never have to wait at crosswalks.

We are tall :)
