For some insane reason, comic book writer Ivan Velez Jr. pitched the idea of a Casper/Ghost Rider crossover to both Marvel and the makers of Casper with a full outline, possibly to silence the howling banshees in his mind. Velez imagined a scenario in which an evil villain replaces Richie Rich's father and shakes up the Harvey Comics universe so badly that Wendy the Witch casts a spell to bolster Casper's powers (what powers he possesses beyond being a joyless specter of our own mortality remains unclear).
At any rate, Wendy apparently casts too much magic and accidentally summons Ghost Rider, transporting Casper to a heroin-soaked puddle in Hell's Kitchen in his place. Casper somehow manages to thwart a bank robber, while Ghost Rider presumably rules the Harvey universe until the two finally switch places again, leaving behind a legion of young Casper fans with a literary shell-shocking usually reserved for Watership Down and Old Yeller.
"Wendy ... the s**t I've seen ... the s**t I've done ..."
How We Were Spared
Marvel signed off on Velez's pitch, because as the fire-peeing scene in the latest Ghost Rider movie clearly demonstrated, they do not give one single s**t about making the character look ridiculous. Harvey, perhaps fearful of how fans of Casper and Richie Rich would react to a tortured servant of the devil suddenly appearing in the pages of their comics, decided to pass.
We should mention that this wasn't far removed from another batshit insane crossover premise that actually made it to print, when Archie of Archie Comics crossed paths with the Punisher, who sticks an Uzi in Archie's face while they both lament their current situation.
Frank Castle's lament takes the form of unprovoked murder.
