Must try harder is the clear message for Lastminute.com founders Brent Hoberman and Martha Lane Fox as they are summarily dismissed with a "next" in this video to encourage school children to learn to code.
It's well worth its two-minute viewing time as other high profile dot.com names are also quickly despatched by the team of kids put together by the Code Club initiative.
Hoberman and Lane Fox can at least take some comfort from the fact that other illustrious names such as YouTube founder Chad Hurley and Tim Berners-Lee get the same treatment.
