The veteran Welshman opened the scoring in Sunday's 2-0 win over Everton, with Robin van Persie adding the second as United went 12 points clear of Manchester City in the title race.
It means Giggs has extended his record of scoring in every Premier League season. And, including the two Football League campaigns he was involved in before the big switch in 1992, the 39-year-old now has 23 unbroken years of league goals behind him.
The milestone is yet another in a staggering career, quite unparalleled in the modern-day game.
And Ferguson admits he does not know how much more he can say about Giggs' talent.
"I think the superlatives have all been used up," said the United boss. "I don't think he needs any himself.
"His legacy lives on, he is just a fantastic human being.
"Again at 38, or is he 39, maybe even 40 he is up and down that pitch all day. He has fantastic energy for the game. It is wonderful to see."
