This is nice, from Alice B:

A brief culture blog

The beginning of Beethoven 5. It sounds exactly like someone going "uh-oh" (with a stammer).

Then they realise it's even worse than they thought, and drop in pitch slightly. "uh (uh-uh)- ohh..."

I noticed this because I heard kids singing it. Whether they got it off some smart-ass cable cartoon or made it up themselves, I don't know. Still, cool.

Indeed.
