Kids WB Crazy Takes (early 2000's promos)
Kids WB Crazy Takes were a collection of promos for shows on Kids WB. They took the form of outtake reels, with clips from the shows being edited to make it look like the "actors" were having goof-ups. They were shown in the early 2000's, but very few have resurfaced. One promo features Joey from Yu-Gi-Oh trying to say his lines when his hair keeps falling over his face. The only other Crazy Takes video on YouTube is a more general one, featuring Uncle Chi from Jackie Chan Adventures repeatedly messing up an incantation.
According to a YouTube comment on the Joey video, another Yu-Gi-Oh promo exists where Yugi's wig is blown off by a strong wind, revealing him to be bald. The commenter also revealed that characters from Kids WB shows did crossovers with other shows in some of the promos.
UPDATE: September 8, 2016 - Since this page's creation, a number of comments have appeared! First, a Lost Media Wiki contributor claims to have seen a Wolverine promo where Wolverine tries to do a Yu-Gi-Oh duel but ends up getting the cards stuck in his claws. Next, an anonymous user found another Yu-Gi-Oh promo in one of their old recordings in which James peeks out of the bushes as Yugi is having tea. Also, another Lost Media Wiki contributor claims to have found at least one Crazy Takes promo on a Scooby-Doo DVD that he distinctly remembers owning, he said he would find it but he hasn't been heard from since. Finally, another anonymous user claims to have seen a 7th Heaven and Pokemon Crazy Takes crossover promo where Charizard blasted fire on one of the main 7th Heaven cast members, who was drawn burnt in anime style, and also claims that a Youtube user has a video of the promo unlisted.
