There are a couple that I use in places now and again. My friends and I play Rock Band, and our band name is Prescription Strength Assault (our logo is a luchador, but I covered his head up with a big blue and white pill). We couldn't come up with anything serious-sounding, so they turned the naming thing over to me. I never take anything seriously.
Other than Prescription Strength Assault, here are some other names I've got at hand:
Shoot Tasty Everything (I saw this one on someone's T-shirt in a dream I had once, so maybe it's already taken...?)
The Von Schrader Sex Machine
What's the Password (yet again, on someone's T-shirt in a dream I had, might be taken already)
Water the Grass
The Superchronics (actually, you might NOT want to go with this one)
Good luck with your band.
