The moment that How I Met Your Mother's Robin first revealed that she was the Canadian teen pop sensation Robin Sparkles, complete with hit single "Let's Go to the Mall," was one of the show's truly classic moments — not to mention one of my favorite online TV spots of all time.

On Monday, Robin Sparkles is back — this time with a little help from James Van Der Beek as an ex-boyfriend of Robin's who happened to star in the video for the B-side to "Let's Go to the Mall," a wistful breakup ballad called "Sandcastles in the Sand." Variety already has the whole song streaming online, but I'm holding off on listening to it until Monday. It's probably silly, but I want to be at least a little bit surprised.

I did, however, cave and watch some of the video teasers that have been released via CBS and MySpace. From the peeking I've done, I can tell the videos have a great, dated vibe, with a dose of Heidi Montag beach video and an amazingly awkward Dawson-related make-out scene. Can't wait till Monday? You can check out both video teasers if you read more.
