"I had 27 Bottles of Quantum... but I ACCIDENTALLY DRANK ONE!"
Hahaha! That made me laugh really hard.
Collecting those was really annoying. The star bottle caps you have to collect in New Vegas made the Quantum Cola challenge feel like a breeze though.
RE: Dogmeat. In the Broken Steel DLC (while I consider all the DLC pretty good for this game, this one I'd say is a must have for several reasons) there is a "Puppies!" perk, that will bring Dogmeat back everytime he dies. I've read that they added a lot of HP to Dogmeat's puppies so he doesn't die as easily. It was kind of lame how you could be casually walking the wasteland only to have Dogmeat run off after some deathclaw or a entire army of Covenant or something without you realizing it and getting himself killed.
