[Found somewhere in here.]

Occasionally while sniffing around the internest I’ll run across an image that jumps up and bites me right in the crackerbockles, and this is one of them. It’s a patent drawing for an invention technically referred to as a WTF, and is apparently designed with meth addicts in mind. That’s meth as in methane.

Of course there may be other explanations for this new addition to the wonderful world of plumbing abuse, but I’m not about to go all scatological on an Overnight Open Thread.

[Update 29 July 2010 – Here are the patent papers. It’s a lifesaving device. Really.]
