what is the name of that famous painting of two people touching fingers and theres angels and stuff in the background ?

That is "The Creation of Adam" by Michelangelo on the ceiling of the Sistine Chapel. I have seen it copied on T-shirts and in a cartoon in "Playboy: magazine. Both of these have God telling Adam to pull his finger. 

It's The Creation of Adam painted on the ceiling of the sistine Chapel in the Vatican. It depicts God and Adam.

extract from Wikipedia,
