the nanny episode that has . . . also has Donald in it.
Fran calls him 'Donnie'
Donald is also often a topic, as a gag, in a show called 'Just Shoot me' where one of the characters is supposedly his rival.
On The Nanny, as I am sure many know, one of the children is supposedly always having playdates with Ivanka.
Marla Maples actually shows up on The Nanny as a guest star playing herself as well.
