One of our favorite things to do is ask Goofy how Max is doing. Goofy usually mimes that he's fishing. We ask if Max is doing well in school, too ... or if he's surfing.
DS loves to tell Stitch to stay out of trouble -- Stitch usually doubles over in "laughter" (mimed, of course) and makes the "crazy" sign. Speaking of Stitch, we asked Stitch and Pluto to pose together w/DS and Stitch put up a stink, giving Pluto raspberries and throwing sugar packets at him at Ohana's. I'm guessing b/c Stitch "pretended" to be a dog in the movie and now has an aversion to them (?!!?).
I once told Cruella that she is my favorite Disney princess and she said "Dahling, I am a QUEEN, not a princess!" Or, tell Cruella you know where to find some spotted puppies. She'll go on about that as she did w/DS!
When I see Alice, I always ask how Dinah is doing (Dinah is her cat).
Sometimes the princesses talk smack about each other. For example, once we saw Jasmine and DH mentioned that DS had seen his 2nd princess that day. She asked if we saw Cinderella and we said no. She told us that if we saw Cinderella, we should tell her that Jasmine says she's not a good dancer. We saw Cinderella later that day and told her what Jasmine said. Cinderella told us that if we ran into Jasmine again, to tell Jasmine that she's just jealous. It sounds like they're friends and just take these opportunities to have a little fun between them!
I always thank Belle for being a good role model for reading! My students love to read b/c I always mention Belle's love of books.
DS asks Mulan how Mushu is doing.
Capt. Hook once chased me for making Tick-Tock noises at him!
Relate something from that character's movie to them and you're bound to get a reaction!
