The One With All The Rugby - S4-E15
Corrected entry: When Ross, Emily, Phoebe and Joey go back to the coffeehouse after Ross gets the crap beaten out of him, he says to Emily "are you kidding? I just made a man twice my size cry. I haven't done that since I was four and I washed my Dad's Porsche with rocks." But in series two when Richard has a "twinkie in the city" (Monica), Jack Gellar comments on how "I turned fifty, I got the Porsche, you've got your own little speedster." If Jack Gellar was fifty when Ross was four, that would make him around seventy-six. He's looking pretty good for a 76 year-old man isn't he?
Correction: It is entirely possible that Jack had a different Porsche when Ross was four years old.

He would have had to, since he practically destroyed his Dad's porsche with rocks. The current car that he has is in tip-top shape.
