Wrong Number?

"Do not answer a fool according to his folly, or you will be like him yourself. Answer a fool according to his folly, or he will be wise in his own eyes..." -Proverbs 26:4-5

Ok so yesterday as Amy and I were walking to catch the tram I received a rather unusual phone call on my cell phone. A number showed up that I did not recognize, but as I am still adjusting to life here I just figured it was someone I probably knew and pressed the green button, confidently saying, "Hallo!". I then heard an animated voice on the other end, with which I had a conversation that went something like this: (phone ringing to a quite lovely classical ring tone...)

Me: Hallo?
Unknown Caller: Hallo...[indistinguishable German]
Me: Uhh...hallo?
UC: Hallo?
Me: Hallo!
UC: [more indistinguishable German]
Me: uhh...bitte? (the word used here to imply you didn't hear/understand and the other person should repeat or reword what they said...I've been saying it a lot since moving here)
UC: Oscar?
Me: haha...umm...no...this is not Oscar's phone.
UC: Wo ist Oscar? (where is Oscar)
Me: I don't know...he is not here...this is my phone (thinking: do Germans say, "You've got the wrong number" in situations like this? I have no idea)
UC: [even more indistinguishable German]...Oscar?
Me: No...Oscar ist...nicht...hier...? (Oscar isn't here)
UC: haha...wo ist Oscar! (where is Oscar)
Me: Uhh...(I give up!) ich spreche kein Deutsch. (I don't speak German)
UC: Warum nicht? (why not)
Me: (what! why not?!) haha I don't know...err...ich weiss nicht...? (I don't know)
UC: uhh...English?
Me: Yes! (since I've been speaking it all along)
UC: Where is Oscar?
Me: This is my phone and there is no Oscar here (umm, I really feel like I'm repeating myself)
UC: no Oscar?
Me: ...You have the wrong number...? ...Sorry...
UC: Wrong number? Oh.
Me: Ok bye...
UC: uhh...ok. [click]

So if anyone knows where Oscar is please contact me. Then next time I'll be so ready to tell Mr. "Unknown Caller" where to find his missing compadre...ha!
