There's always the classic cartoon sneezes. Like Scooby Doo and the looney tunes and stuff.
But one the (short) cartoons that stuck out to me was one about this little blue car that was a really "pretty" car. She was pretty expensive and was bought by some young guy (who was probably going through a mid life crisis lol). She lasted him awhile before she broke down and he sold her. She was bought by other people in used car lots and was treated pretty poorly. There was a scene where she's out in the snow and she sneezes. I was always obsessed with that scene, never knew why, but that's the reason I liked watching that cartoon haha.
Susie the Little Blue Coupe!! I just recently discovered this one for myself a few years ago, but I think it's absolutely adorable.
Velma's from Scooby Doo always stuck out to me because it's the first time I really remember seeing sneezing on TV after coming to terms that I liked it. And I was
really young when that happened.
If we're talking old as in classic... I've actually been thinking about Goofy's
Cold War short a lot recently. I didn't discover this one until maybe 2012, but I'm endlessly amused by the setup.
And to piggyback on that, Disney's
"How to Catch a Cold" video (this is the new one; there is an animated one with a similar premise from the 50s) always struck me as something incredible. I actually watched this one in school in my 3rd or 4th grade health class. I think the teacher just put it on to fill time, but it obviously always stuck with me.
