Cursor erasing graphic - how to?

Hi,

A manager at work has agreed to shave his head if we meet the quota he set out. I would like to make a gag of this in flash. Here is what I though…

Take a picture of his head with hair and erase it with a cursor hair shaver to show a shaved head in the part the shaver went over. My question is how to make the hair part go away where the shaver had been and how to do a cursor buzzer. Any ideas would help.

Thanks!

If you get two different images, one with the hair on and another without, i can help you with the ereaser part

OK thanks.
