If this whole acting thing ever dries up for Jennifer Garner, it looks like she'll be just fine. She revealed on 'Late Show with David Letterman' (Weeknights, 11:35PM ET on CBS) that she has an entrepreneurial mind dating back to her college days, if not earlier.

Her methods might have been a little questionable, as she was using school equipment and stealing elastic from the theater department, but you have to be impressed with the ingenuity she and her roommate had in developing a scrunchie business out of it.

"We made so much money," she said. In fact, according to the actress there are still people out there who've hung onto the scrunchies they bought from her.

But her business acumen didn't stop there, as she dreams about business ventures as well.

"I used to watch your show every night and I used to have dreams that you and I had a jewelry company," she told Letterman. "We designed jewelry together."

It's certainly a rather specific vision, but it looks like she was on the money. "I would love to design jewelry," Letterman said with a laugh. Considering celebrities have been putting their name on jewelry and perfumes for years, it's not that much of a stretch.

Would you buy a Garner/Letterman original piece of jewelry?
