You would think after 90 years of being together that people would get the hint that Minnie Mouse is off the market, but video of a dad proposing to Minnie in front of Mickey Mouse if going viral because of Mickey's reaction!
You can see the video below, but as soon as the dad gets down on one knee Mickey gets all sorts of protective over Minnie! He kind of has to though because characters are trained to never break character, which in this case means not letting your wife say "Yes" to another man's proposal.
Costumed characters aren't allowed to talk while in character, but Mickey did a great job of using non-verbal communication to ask why the dad was proposing. Hopefully no one else gets any ideas of moving on Mickey's girl!
