Us vs. The Thistles - Revenge of Us!

From an email conversation with Mindy:

R: Next weekend is fine for me as far as I know right now. *grins* But yeah, count me in with helping - it's personal between me and those damn thistles now!

M: Alright so next sunday we will launch a counter attack on the thistles of doom!

R: This time It's Personal!

M: We're gonna need a soundtrack...

So, randomly on a Friday where I really don't want to work, by all accounts... what song do you consider Indispensible on the Crowning Moment of Awesome Sountrack?

(YouTube links will have to wait until I get home, since they're blocked here. *pouts*)
