I am an unashamed fan of the following:
Cheesy Scientist Super Villains (in appropriate context)
Gratuitous Shots of Lab Glassware (in appropriate context)
Gratuitous Shots of Nathan Fillion (aka Captain Tightpants)
Alas, I have never seen them all combined.
Dr. Horrible's Sing-Along Blog is a three-part miniseries defining the "Superhero Musical" genre. Think "Once More with Feeling" with more silly if you are a Buffy fan. I strongly recommend checking this one out.... where else can you find a musical with songs like "My Freeze Ray" and lines like "I have a PhD in Horribleness*". (Actually there are many much, much better lines, but I don't want to spoil anything.) The music is actually pretty good too. (If you like this kind of thing. I looove this kind of thing.)
Available free until this Sunday only!
*Can I have a PhD in Horribleness?
How about Naughty? Dr. Naughty.
Er, I better go before I wind up saying something Silly.
