I just checked and not even Google has any results for "Zeberpupin". The system is obviously highly classified. No one else in the company is allowed to even know of its existence. Not only is Wally the only expert on the system they have, but they would find it impossible to replace him.
When I put in for retirement they looked at my programmes and said "What the hell is that?" "It works," I said. They allowed me to retire anyway. I heard two years later they are still trying to figure it out by hiring expensive consultants. Keep Wally.
