101% Whizbang! (with Henry and June), or more simply 101% Whizbang!, was a short-lived Friday night block hosted by Henry and June from KaBlam! that ran between early to mid-fall of 1999. The weekly event mainly consisted of reruns from various Nicktoons and live-action series, though its first week on the air was dedicated to one of the first ever marathons of SpongeBob SquarePants. For most of the block's lifespan, however, it would be known as its temporary Halloween-themed rebrand, (101% Spooky Whizbang![4]) airing fittingly themed episodes of series throughout October of that year; albeit, that version did not air any episodes of SpongeBob itself. A week after the block's closure, it would immediately be replaced by U-Pick Friday, which was almost the same (even sticking with the same hosts) - except it featured the ability to vote for the program one wanted to watch.[3]
SpongeBob and The Angry Beavers are tied for the most aired series of this event, with four episodes (totaling eight segments) aired. Angry Beavers, albeit, did repeat one of its episodes, ("Spooky Spoots / Up All Day") thus technically making SpongeBob the show with the most uniquely aired episodes.
Rugrats, The Wild Thornberrys, Kenan & Kel, and Doug tie for second place, with two episodes aired - albeit, Rugrats repeated its episode ("Candy Bar Creep Show / Monster in the Garage") twice.
Hey Arnold!, Are You Afraid of the Dark?, The Journey of Allen Strange, Cousin Skeeter, CatDog and Rocket Power tied for third place, all airing one episode.
