I am usually up at all hours (as I am now), watching WCS and Lindy Hop videos on Youtube. That and the "Love Letters to Carbs". Another favorite (suggested to me), is the Dilbert cartoon about "The Knack".

For reference, I've posted links to examples of how I regulate my GPA to prevent it from becoming too high ;

A brief note about the dancing before you scroll any further; these videos are of some of the best dancers of their particular style, so if you (hopefully) decide it looks interesting, don't be discouraged if you don't look like that on the dance floor (I'm very much a beginner myself as well). As for the love letter to carbs, there are a few obscenities, so I haven't linked to it here. Rather, it's easily found if you search "Love Letters to Carbs" on Youtube.
