What seems to be your challenge Mr. Smith?
Well Doc, I’m a compulsive liar.
You’re telling the truth right now aren’t you!
No.

Mr. Smith one of your statements has to be the truth!
Not really!
And why not?
I’m omnipotent

So you have a God complex whereas anything is possible?
No, that’s my name.
Your parents named you omnipotent?!?!
No

Mr. Jones (skeptical voice)
What?
You’re not telling me the truth here!
That’s what I said in the first place Doc.

Yes, you did say that. When did you recognize that you’re a liar?
I’m not a liar.
Yes you are, you’ve been lying to me.
No I didn’t! I think you’re projecting. You’re the liar!

I’m the Doctor and you’re the liar.
I knew this was a waste of my time; I’m leaving! Good luck with your problem Doc!
Well at least you don’t hold grudges!
Yes I do! (As the door closes behind him).

Is it Friday yet?
