On the back cover of The Year of Roosevelt Franklin, McMahon's review of the album is quoted among others.
- The unmade Muppet television special Johnny Carson and the Muppet Machine was to have included a scene with a talking boulder bearing McMahon's image.
- Guy Smiley spoofed McMahon in the 1974 special Out to Lunch in a Tonight Show parody with Cookie Monster playing Carson.
- In the Muppet Babies episode "Happy Birthday, Uncle Piggy," McMahon appears (voiced by Frank Welker) to report that Johnny Carson is unavailable to perform at Uncle Statler's birthday party. Baby Fozzie performs in his place, as introduced by footage of McMahon lifted from The Tonight Show.
