Water Bottles

I don't want to appear ungrateful when we get a free gift at work, but does it really have to be another fricking water bottle?  I'm looking in my cupboard and I've got 6 of them now, all freebies.  And I think I've got another 2 at work.  Don't get me wrong, some of them are very high quality bottles.  But of the 8, I think I've maybe only ever used 1.  So if you'd like a water bottle for a Christmas present, just give me a shout...
