The good news is he can't get into the house. Not unless you let him in. NEVER do that! No matter how friendly he acts. Arkvoodle here (yes, that was really his name) looked all pitiful and lonely. But don't fall for that sad, no-eyebrow look!
---Arkvoodle! We do NOT have openings for research subjects at the present time. Please leave!---
But of course, Arkvoodle didn't leave. He took out his scanning device and crept around the yard, collecting data on the family...especially the males.
Which brings us to the important part of getting rid of aliens. Whatever the cost, find yourself a genie! Preferably one with bouncer experience.
Now command your genie to banish that invader! In a split second, without murder or mayhem, the alien will vanish without a trace! ...We don't care where he goes. We're just happy he's gone.
