Homer Simpson VS. Peter (or whatever the dad's name is) from family guy.
Vader's wife was very pregnant when she died 19 years ago. All of a sudden a 19 year old who is very strong in the force and has a distinct resembalance to him in his younger days rolls in from Vader's home planet with his old Master Obi-Wan (Who was the ONLY other person preset at the time his wife died. And to boot, the kid's last name is Skywalker.
So in answer to your question, he knew Luke was his son because his name is Darth Vader, and not Darth Retard.
Location: Aalborg, Denmark. Otherwise Talnivarr, EU server.

We all know the outcome of this one .
Either the Spoon will show up, and claim lordship over it, or the slaves will kill Rhett before the Spoon comes along and claims lordship over them. Either way the Spoon wins. .
