"Snowwhite and the Seven Dwarfs" joke

Snowwhite and the Seven Dwarfs are roaming in the forest when
they come across a lake. the water was enticing and Snow-white decides
to take a bath. So she tells the Dwarfs to turn around while she is
preparing to take the bath. Dwarfs protest vehemently and then
Snowwhite relents and says that when i get into the water and u
hear the splash, u can turn around.
Snowwhite undresses and as she is about to jump into water, at that very
moment she is startled by a frog who jumps into water before she can.
The moment the dwarfs hear the SPLASH, the Dwarfs turn around and see Snowwhite standing NAKED.
