A moderately expensive joke

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...

 ...and it doesn't expressly say that it has that warning on the backside. Other sites, however, do show photos of the backside of the bottle...

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.

Is a red bottle without the logo worth paying the extra $20 for?

I'm thinking that it might be.
