I remember some show, probably a cartoon, had a joke with two people looking at a magic eye poster and not being able to see the picture. Then a character crashes into the poster and one of the people goes, "Oh, now I see it!"
I thought maybe it was Phineas and Ferb but I can't find any scene that fits, but the comedy style was quite similar.
