Well, both Panis and Fisichella have a GP win. In odd, wet-race, crash-ridden circumstances, too! Both of them suffer form being better drivers than racers, which both are good at bringing the car home.
Panis was lucky (Monaco '96), but he's come home in the top three when everyone else wasn't there, so it's hard to say he didn't deserve it. Fisichella had the most 2nd places of any other F1 driver in history with no wins until this year's Brazilian GP. I am rather surprized they are both still at it, considering the lack of teams and wealth of up-and-coming drivers, but neither can be criticized for dangerous driving, slow lap times, nor being pay-drivers.
When you compare lap times, Alex Yoong really wasn't the worst of the worst all-time. Far from it. He was only a second or two of the pace of his teammate, who happened to a bright star named Mark Webber. In fact, I believe there were some occasions in '02 where Yoong had out-qualified the entire Jaguar team.
