Interactive "punch the monkey" style banners? Tutorials anywhere? examples?

The company I work for wants some interactive banners, things like “punch the monkey” or shooting a basketball or any of those other mini-games that they put in the flash banner ads.

I am an AS noob, but pretty decent with flash animation and timelines. Is there anything out there that could show me how to make one of these banners, or a tutorial or example file I could learn from?
