If I remember correctly, Ben Stein was the voice of the Rabbi. Peter Riegert as Max Weinstein. Maybe they recut the episode?

'TIS THE SEASON TO BE JOLLY WHEN A FA-LA-LA-LA-LA- FULL HOUR OF "FAMILY GUY" AIRS FRIDAY, DEC. 10, ON FOX
Including a Never-Before-Broadcast Episode
Christmas comes early this year when FOX airs a freakin' special block of back-to-back episodes of the animated comedy FAMILY GUY Friday, Dec. 10 (9:00-10:00 PM ET/PT).
In the episode "A Very Special Family Guy Freakin' Christmas" (9:00-9:30 PM), the holiday season gets off to a rocky start for Peter, who can't find time to watch his favorite Christmas specials like the classic "KISS Saves Santa." But when he accidentally gives the family's presents away, the Griffins must hit the mall to buy last-minute gifts on Christmas Eve. Brian stays home and gets caught in a sappy Christmas tree crisis, which causes Lois to lose her holiday cheer � and her cool. KISS band members make guest voice appearances as themselves.
In the episode "When You Wish Upon a Weinstein" (9:30-10:00 PM), airing for the first time on broadcast television, Peter buys volcano insurance and Lois becomes fed-up with their constant money problems. When Peter wishes for financial guidance, Max Weinstein (guest voice Ben Stein) comes to the rescue. After meeting Max, Peter decides Chris could become smart and successful if he converts to Judaism, but their plans for a "quickie" bar mitzvah in Las Vegas are quickly foiled by Lois.
