Some of the extra missions you found the most challenging? (Grand Theft Auto: Vice City)

We are not talking about basic and not about the side missions.Meaning: firefighter(12уровней),paramedic(12 levels),COP(12 levels),pitchperfect(10уровней),taxi driver(100пасажиров),Iceman(50 servings).To me the most difficult seemed to work as a taxi driver to earn 100 passengers is not so easy.
