Get some perspective

Yeah, poor Carl. Oh wait, you've got a castle. Man up, you rich jerk, and try to think what it's like for us regular people who get chased out of a town. Self-involved jackass.
This may seem cruel, mocking and unpleasant to you.
And I do not disagree that it has its vile and childish side. But comedy has no friends, mad people are funny, and it's not news that I'm an arsehole sometimes.

“See ya, Dick.” How perfect is that? It’s short and snappy - and edgy, the way all the kids today like it. Can’t you see that on mugs and t-shirts and movie posters? Most importantly, it works with the character. It’s the perfect catch phrase for a guy whose main power is running away from you. “See ya, dick,” as the bad guy chokes on his dust. Or when the Justice League needs him to go on that super-fast errand: Superman: Flash, we need that isotope, now!Or maybe just as he delivers the finishing blow to an evil mastermind:
Flash: Sure thing! See ya, dicks! [ZOOMS AWAY]
Bad Guy: It’s too late, Flash! No one can stop me now, not even you!That’s the best part of the new catchphrase: the versatility; he can use it anywhere. It's appropriate when the world is in danger, or when he hears his wife looking for him to clean the mess in the kitchen ("Uh-oh. See ya, dick"). There you go DC, it's like a license to start printing money. You're welcome. Just remember to send a little this way. I'll be the guy wearing this t-shirt:
Flash: See ya, dick. [FLASH PUNCHES VILLAIN] SFX: POW!
