"Wouldn't it be cool if I could fuse with myself and become two of me, huh, Dad?!"
The Fusion Dance (メチャカッコ悪い!?特訓変身ポーズ, Mecha Kakko Warui!? Tokkun Henshin Pozu) is the sixteenth episode of the Majin Buu Saga and the two hundred forty-seventh overall episode in the original dubbed and the uncut Dragon Ball Z series. The episode first aired on November 23, 1994. Its original American air date was October 1, 2002.
Goku, who used up all but thirty minutes of his Earth time by fighting Majin Buu, gets back to the Lookout to teach Goten and Trunks the Fusion Dance. Majin Buu is seen using Innocence Express through West City.
Piccolo asks Goku to send Gohan his regards in Otherworld. He starts by having them equalize their power levels, both as Super Saiyans and as normal Saiyans. After showing them the proper form to begin the fusion dance, he then shows them the most difficult part of the dance: A series of three delicate poses that, when performed properly, create a single being of incredible strength. The dance, however, is so ridiculous that everyone except Goku questions the dance's potential.
"I've never seen Goku so weak before... That Super Saiyan 3 transformation must've really taken its toll..."
