Bicycle chain "slipping".

[RossJarvis]

I'll go out on a limb and claim it's got sealed for life, super duper tough as you like, last forever, never needs oiling, teflon based, back flatened on a waterstone, hollow ground, stropped on a fishermans belt, NASA designed, German engineered, gold plated, fur lined, ocean going, bestest ever, can't be beaten, Sheffield steel, longest family heritage, used by all the greats, wear resistant, heat treated in the sun, quenched in the tears of angels, bearings throughout.
I'd like to see someone "one up" me on that one 8)

You missed out "lip-smacking, thirst quenching"
