Christoph Waltz: Oscar-winner sings on Austrian children's show at age 21 - Watch!

Before he first collaborated with Quentin Tarantino in 2009's "Inglourious Basterds," Christoph Waltz was best known as an Austrian television star.

He got his career kicked off in 1979 with the role of Eduard "Ede" Bredo in "Parole Chicago," but two years prior he had made a brief appearance on the Austrian children's show "At the Dam." Ever wondered what a 21-year-old Waltz looked like? Well, you're about to find out.

After watching the above video, it's no wonder Waltz decided to sing when he hosted "Saturday Night Live." Despite the fact his rainbow one-piece and bulge are a bit distracting, Waltz is undeniably adorable here. Thanks to Mashable for the heads up about the video.
