Lots of strange data

I've been getting a lot of strange data. I went back to·basics, and wired a simple pushbutton circuit.(onee wire to Vdd and one to P0. I used this code:
As soon as i click run, I get a ton of a's. So I disconnect Vdd. And I still get A's, even when I restart. Perhaps something with my circuits are wrong,·because this has happened a lot lately.
I tried this on a BOE and a home work with no luck.

IF (IN0 <> 0) THEN
DEBUG "a"
endif

A pushbutton wired to P0. That is it. I used the same code as above. As soon as I touch the pushbutton, the aa's appear, but now they will go away when i release. The strange thing is there is no Vdd attached!

The pins are very sensitive and they are picking up electrical noise caused by your body.

Does that mean that I could hook up a large plece of metal to a pin, and have it detect my motion? Is this the basis of a PIR sensor?
