Take a yoga class, you'll be able to do that squat in no time. 
Now, how yer gonna get yer big ol' butt into the rim and get the right seal is beyond my expertise.
I've been thinking about it and if this was to catch on - you realise there are only two possibilities:
1:) every one starts using anal gas and the term "Smell the Bumper" becomes a dead or dying cliche.
2:) We really go to the dogs (literally) and the term "Smell the Bumper" takes on a whole new meaning and is adopted by the Local and Federal Authorities as the new form of Identification. . . No more stoping people at roadblocks. Just motorcycle cops with sniffing devices up and down all the major road ways.
You'd probably see legistaltion inacted making it illegal for you to fill your tires after certain meals or when you had a case of the scours. . . Could result in false ID's. . .
