We sleep soundly in our beds because rough men stand ready in the night to visit violence in the course of bicycle delivery

Rest assured, dear customer, that whatever adverse conditions may be thrown up in their path, the Riddled delivery staff are steadfast and stalwart and trained for every circumstance, and your bicycle will be delivered.

A little rain? Floods, mud? Bridges washed out and slippery tree-trunks the only way over the raging torrent? Biko man is always intense.

The forces of anti-bicyclism may be strong in these lawless days, but the Riddled delivery staff are stronger. They are ruthless. They are heavily armed, and they are not afraid of weird colours in the sky. They realise that a sacred charge is in their care, for you, the customer, are waiting for that bicycle.
Depending on the state of the county roads and the operations of the Mollycule theory, you may find that the bicycle upon receipt contains 10% or more of atoms from the delivery rider, who is conversely 10% or more bicycle. This contingency is covered by clause 16 of the rider codicil of the purchase contract, where the helpful Table II lays out the available options for different proportions of atomic interchange.

Do not attempt mollycule interchange with Table II, however helpful it becomes.

Must credit Ptak Books, albeit in vanishingly small print.
