Here's something silly I liked to play around with way back in the days when I was at TVTropes. Take any media. TV show, movie, game, book, franchise, etc.

Add or remove a single letter. You can also make a replacement by adding AND removing one, but the important thing is that the net difference from the original title is one letter.

Post what you get and make a short synopsis of the stupid pun that is the end result.

Examples off the top of my head (You don't have to have the special markers/colors or include the original—I just did it for the sake of clarity):

Saving Private Ryan -> Shaving Private Ryan: A comedy about a draftee who wants to keep his mullet rather than have a regulation military 'do. (Adding a letter)
Teen Titans GO -> Teen Titans GT: The wildly unpopular sequel series to the original Teen Titans, in which Robin is wished back to being a kid. (Replacing a letter)
Luigi's Mansion -> Luigi's Mans_on: Luigi's being stalked by a crazed, homicidal cult leader. You have to fight him off. (Removing a letter)
Yoshi's Story -> Yoshi's S_orry: Yoshi goes on an epic quest to atone for his sins. (Moving and changing a letter)

You know, things like that.

Hey this is actually a pretty clever game

Devil May Cry -> Devil's May Cry: A tragedy where Satan must prevent the death of his loved one before she is destined to die on the 31st of May

OR

Devil May Cry -> Devils May Cry: Starring Dante, this horror game is so evil and twisted that even the most cold hearted people will cry by the end

Dragon Ball > Dragon Balls
Take a guess.

Boku No Pico -> Goku No Pico: ...It's literally just the first couple episodes of Dragon Ball.

And while we're going there...

Fritz the Cat -> Fritz the Car: Pixar's ill-fated attempt at risqué adult animation.

The Rion King: An racist version of the Lion King.

Over the Hedge -> Over the Edge: An inspiring, heartbreaking story about animals who strive to change their edgy personalities

WALL-E -> WALL-: A movie about a sentient wall. (Most likely Trump's.)

Shadow the Hedgehog -> Shadow the Edgehog: Simply a more accurate title for the same game and character.

Legend of Zelda: Ocarina of Time -> Legend of Zelda Ocarina of Tim: Link goes on a lengthy quest to get the ocarina of some guy called Tim.

Steven Universe --> Seven Universe

It's a new show about the seven universes (yes, seven) of SSB.

I'm too lazy to think of them so..
Mario (counting DK and Yoshi)
Zelda
Kirby
etc. etc.

Doctor Who -> Doctor Whom: The interdimensional grammar police!

Mario and Luigi Dream Team -> Mario and Luigi Dream Tea: The normal game except the villains are after a legendary fountain containing the titular Dream Tea which will let them control everyone's dreams.

JoJo's Bizarre Adventure > JoJo's Bizarro Adventure
it's the whole thing except it's the complete opposite.

Adventure Time ---> Adventure Tim - Adventure Time but Finn is renamed Tim.

Fairly Oddparents -> Fairly Oldparents: The comedic hijinks of a young child born to an elderly couple.

Star Fox -> Star Fax: Fox sends photocopies of himself across the Lylat System.

M*A*S*H -> S*M*A*S*H: All of your favorite Nintendo characters crack jokes to cope with the harsh reality of a gritty war zone.
