Goten's Disappearance

What Happened?
Right after Goku is hit so hard in the dick, he, screams as it fades into the future of the Buu Saga, as the caption says. [Several years later...], Adult Gohan says: "All right, Goten, its your job to chuck these as hard as you can so I can be all trained up to face off against Dad in the tournament!" Gohan then says: "Now stand behind that line and-" but before he can finish his sentence, Goten fades into dust. Gohan quickly says after he starts turning into dust "Goten" as history wipes out Goten. Gohan proceeds to say "What was I doing here?" as it fades into the present with Goku faint screeching and proceeds to pull a Return Of Cooler's Revenge 2: The Reckoning and say "He punched me in the dick, why, why did he punch me in the dick"
