As I tried to post before but in the wrong thread...

Possible lines:

Obi Wan: "I haven't gone by the name Obi Wan since I betrayed and murdered your father."

Luke: "You know him?"

Obi Wan: "Well of course I know him!"

^ Great idea! I've made a few tweaks based on the Obi-Wan/third-person gag...

BEN: Obi-Wan Kenobi...Obi-Wan? Now thats a name Obi-Wan hasn't heard in a
long time...a long time.

LUKE: I think my uncle knew Obi-Wan. He said Obi-Wan was dead.

BEN: Oh, Obi-Wan's not dead, not...not yet.

LUKE: You knew Obi-Wan!

BEN: Well of course Obi-Wan knew Obi-Wan. Obi-Wan's Obi-Wan! Obi-Wan hasn't gone by
the name Obi-Wan since Obi-Wan betrayed and murdered your father.

LUKE: Then the droid does belong to Obi-Wan.

BEN: Obi-Wan doesn't seem to remember ever owning R4. Very interesting...

BEN: Obi-Wan thinks we'd better get indoors. The Mushrooms are easily startled
but they will soon be back and in greater numbers.

^ That'll be 17 Obi-Wans in as many seconds lol
