I didn’t realize how many times she has appeared on different versions of the show: 110, according to Strahan, including tonight. Later, Ms. Moreno was asked if the show had changed a bit since her last visit.
That number seems a bit high to me, so let's do some fact-checking...
April 30 to May 4, 1973 (there's 5 appearances)
December 4 to 7/December 10, 1973 (brings us up to 10)
January 7 to 11, 1974 (15)
March 13 to 15/March 18 to 19, 1974 (20)
July 29 to August 2, 1974 (25)
[two appearances in the 1974-1975 season of The $25,000 Pyramid, bringing the count to 27]
February 17 to 21, 1975 (32)
[two appearances in the 1975-1976 season of The $25,000 Pyramid, bringing the count to 34]
August 11 to 15, 1975 (39)
January 26 to 30, 1976 (44)
May 31 to June 4, 1976 (49)
[two appearances in the 1976-1977 season of The $25,000 Pyramid, bringing the count to 51]
January 31 to February 4, 1977 (56)
[two appearances in the 1977-1978 season of The $25,000 Pyramid, bringing the count to 58]
October 24 to 28, 1977 (63)
September 4 to 8, 1978 (68)
November 13 to 17, 1978 (73)
February 23 to 27, 1981 (78)
November 29 to December 3, 1982 (83)
March 21 to 25, 1983 (88)
October 3 to 7, 1983 (93)
January 3 to 6, 1984 (97; only 4 shows that week)
May 28 to June 1, 1984 (102)
August 11 to 15, 1986 ($100K) (107)
September 1 to 5, 1986 ($25K) (112)
April 1 to 5, 1991 (117)
And this isn't even including the possibility of her having been on the 2002-2004 or 2012 versions.
OK, turns out they actually lowballed the number. Color me surprised.
