Sneaky Tom is a reaction image series based on a scene from the American animated TV series Tom and Jerry in which Tom slides his way through a door with a mischievous smirk on his face.

In the original clip taken from the 1950 episode entitled "Jerry and the Lion," Tom sneaks behind a door while doing an evil laugh as he plans to catch Jerry. Shortly after, Tom closes and locks the door as he gets outsmarted and physically beaten by Jerry off screen.

The earliest known appearance of the image can be traced back to a tweet posted by @Tweets_2dope^[1] on July 27th, 2013, although its usage as a meme didn't begin until early 2016.
