In what I'm guessing is a reference to a joke in Portal, water bottles with the following warning are being sold: "WARNING: May cause diaphoresis, micturition, and acute tissue hydration."
See, it's funny.
Sadly the bottles being sold by the Portal folks look kind of lame and have a giant Portal logo on one side...
At $9.99 plus S&H, that's not a bad price for a decent little gag, but I really don't like the Portal logo.
For a scant $31.05, however, I can get the same warning on a bottle of my chosen color thanks to Zazzle and can change the bottle size for an extra buck - or change the text color and other stuff, too.
I'm thinking that it might be.
