M.,
I found this on the internet:
Ballpoint Ink Stains
Lay the stained area on top of a clean dry white towel. Apply rubbing alcohol to the ink stain and blot with another clean white cloth, removing the stain as you blot. Rinse thoroughly.

Apply your normal liquid laundry detergent onto the ink stain and allow the garment to sit for 3-5 minutes.
Wash in the warmest water that the fabric can tolerate.
Before drying, double check to make sure the stain was removed. If not, repeat the previous steps until it is.
Good luck!
p.s. I have also hear about hairspray and I think I remember hearing to try milk.(?)
