The original "ad" basically said:
I have raccoon eggs in my garage...at least I think they are...free to anyone who wants to come get 'em....momma gone during the day.
The Response:
"Raccoons...raccoons do not lay eggs sir. If you have eggs in your garage big enough for a raccoon to have given birth to (given that they laid eggs in the first place, which they don't) I think you might want to relocate them off your property. Who knows what they are."
The response was the best part.
The original poster might be the same guy who found Bruce's cat.
