The shape I'm in

The first law of sales-trading is that you can sit at your desk all day and do nothing but the minute you pop to the loo you will miss an order. Since Double O’Flynn my sidekick became Flyaway Flynn last week I am now more vulnerable than ever to this cruel but immutable rule. Either I need to patent some new form of seating which incorporates lavatorial facilities or I need to condition my notoriously incapacious bladder to withstand unbroken stints of equity salesmanship lasting almost 10 hours.
