Why would I want to have cucumber water? I mean, I know the reference, but it wasn't a huge part of the show. I can see drinking coffee while watching the show, but the cucumber water... not so much.
I don't have anything that I always have with me, but I generally watch the show downstairs on our humongous T.V. so I always have my blankie (yes, I'm 18 and still have a blankie. There is no shame). I also usually have a pillow of some sort. If I watch it in my room on my portable DVD player, then I have my pink bean pillow. It's generally just my blankie, though.
