Anyway, I'm suprised no one like you here has mentioned this one yet (unless you did and you overlooked it), but while we're talking about Dexter's Laboratory: Ego Trip, let's add the whipping scene between Executive Mandark and Future Teenage Dexter, one of the most disturbing and chilling animated scenes you or I've seen.
It started out with Teenage Dexter getting up, taking a bath, brushing his teeth, putting his glasses on and eating breakfast, before stopping by onto his computer. He was typing on it, and realizes the time (which is 8:52 am) and that he was almost late for work, so he logs on as Number 12. He has a conservation with his computer, until...Executive Mandark yells, "Number 12, you're almost late for work this morning!"
Teenage Dexter tries to speak but Mandark snaps back for him to report to his office immediately. Teenage Dexter was then chained to his chair and the chair and Teenage Dexter took off all the way to an giant, M-Shaped door. When the clock strucks 9 am, Teenage Dexter was pulled over to an office room for women (I don't like the looks of these women, 'cause I don't care about them!), until he stops and looks at a Head Secretary who said to him, "You're expected."
Number 12, aka, Teenage Dexter, was then pulled closer, scaring away some flamingos, pulling closer through paradise (including a tennis course) and pass some pea*****, pull through a bridge until finally, (Here's one of my favorite parts in Ego Trip, you guys) He stopped in a Jungle-infested swimming pool area-like paradise, where, (Are you watching?) those beautiful, pretty, lovely, hot and pretty girlies (one, blonde haired, the other, black haired) are washing Mandark's feet, wearing erotic bikinis. (wolf whistles)

Boy, I wished I could flirt with and kiss either that blonde or that brunette, and I'll marry either of them and have children.

I'll show a pictures of those beautiful, hot, pretty, and lovely sweeties who give Mandark a bath!
Well, Look at them, they're beautiful, hot, pretty, and lovely. I love those girls, 'cause they're hot! It's not because they have big breasts, it's just because of their closed eyes and red lips! Here's them with me digitally editing myself with them.
Well, that's all I've got for you. Anyway, Mandark said being almost late for work again is such a pity, and uh oh! when he got up, he exposes his ass to the whole wide world!!! :ack: But that's okay, he's just wearing a man thong! He claps his hands, then those beautiful, pretty, lovely and hot girlies who scrubs Mandark's feet, got up, turn around and run off in the distance in an erotic streak!!! :ack: Man, that half-naked erotic streak from the girls puts me off nowadays!
But that's okay, all we see while Mandark was Teenage Dexter was the arms from those same girls that we've seen earlier, putting deordorant on Mandark's arm pits, cleaning his fingernails, shaving Mandark, poking out his unibrow, and putting his whitey tighty or underwear on! Here's what Mandark said to Teenage Dexter:
Teenage Dexter then got his clothes ripped off and tied to some machine, only to face a laughing, executive Mandark, which is shown for the very first time. The Present Day Dexter, having been caught in the street for unauthorized walking by a security robot, then sees a televised image of Mandark speaking to the workers to join him while he whips Teenage Dexter, and then turns to Teenage Dexter, and he said he had paddling to do, but Mandark refuses (or maybe balks at) to accept his paddling, and so Teenage Dexter turns around, and with the saying of "Now make a wish!" and twice, "Again!" He whips Teenage Dexter three times, and you can see a horrific imag of Teenage Dexter screaming in reaction to the burns from the electric whip, which is repeated twice, while the present day Dexter watches in bewilderment. After the whipping, you can see Teenage Dexter wheezing after screaming, and Dexter turns around and said to us, "That's me." and then collaspes. Mandark appears one more time and then the TV is turned off.
Hope that helps. Beware all that, including the whipping scene between Mandark and Teenage Dexter!
