#1  The Doctor and Craig are fighting the Cybermen silver rat in Craig’s kitchen.  Craig is holding the rat immobile with a cookie sheet from the oven, and the Doctor is riffing about why his sonic screwdriver isn’t working to deactivate it.  In a great line, The Doctor says “that’s OK, I have an app for that!”, gives the sonic a twist, and zaps the rat!  The day is saved!

#2  Adam Savage of Mythbusters steps into a dance cage, and boogies down to the Dr. Who theme while Tesla coils zap him!

Just too cool!
