How many established celebrities made multiple guest appearances on the Jim Lange version of "The Dating Game" as questioners, not as potential chosen dates?

Let's see...off the top of my head:

Michael Jackson
Harold Jenkins (of Little Anthony and the Imperials)
Ken Norton
Maureen McCormick
Barry Williams
Ann B. Davis
Karen Carpenter
Burt Reynolds
Joe Namath
Leif Garrett
Willie Aames
Jaye P. Morgan
Beverly Garland
Jan Murray
Candy Clark

...and some appeared as questioners for someone else:

Dick Clark (choosing for a female AB regular)
Phyllis Diller (choosing for her son)
Marc Copage (choosing for his dad)
Vincent Price (choosing for his daughter)
HR Pufnstuf[!] (choosing for a young boy)

Chuck Donegan (The Illustrious "Chuckie Baby")

All of those people were on MULTIPLE times? More than once?

Forgive me, it's been a long day...LOL...that whittles the field down to a mere 3:

Maureen McCormick
Barry Williams
Burt Reynolds

...along w/someone else not mentioned, Tom Selleck, though I'm not sure he qualified as an "established celeb" at the time of his apperances.

Chuck Donegan (The Less-Than-Perfect "Chuckie Baby")

Cuba Gooding Jr. didn't qualify as an established celeb at the time(other than his father having hits as part of the Main INgredient some 10-15 years earlier) he made his multiple appearances either(didn't he appear more than once on the 80s version)?
