Dragon Ball GT - episode 64 - 18 Nov, 1997

Shenron heals Goku, and explains that he can't allow everyone to overuse the Dragon Balls again, so he is leaving the Earth, and taking the balls with him, planning to return when the people of Earth learn to solve their own problems without using the balls. However, he allows one more wish at Goku's request, which is to repair all damage done to the Earth since the gateway to Hell was opened up by Android 17, as well as revive all the innocent people who have been killed. Just before Shenron leaves, he calls for Goku to accompany him. Goku entrusts Vegeta to take his place as Earth's savior, and as they fly away, Bulma reminisces about her time with Goku. Unexpectedly, Pan finds Goku's clothes on the ground, and Vegeta tells her to treasure them dearly before he and the other Z-warriors leave. Goku stops by Kame House to say goodbye to Master Roshi and Krillin, who has been revived. He also stops in hell to say goodbye to Piccolo, and tells him that he will one day get back into Heaven. As he lies on the back of Shenron, the seven Dragon Balls become one with Goku's body, and he becomes one with Shenron as Shenron finally vanishes. 100 years later, all of the Z-warriors have died of old age except for Pan, Vegeta Jr., Vegeta's descendant, and Goku Jr., Goku's descendant and Pan's grandson, are fighting in the junior division championship match at the World Martial Arts Tournament. Goku Jr. is wearing Goku's clothes that Pan picked up many years ago. Pan looks down and sees the now-adult Goku watching the fight, but when she goes down to find him, he's not there anymore; Pan merely assumes that she was imagining things. As Goku exits the stadium, he flashes back to many of the events that shaped his past, from his adoption by Grandpa Gohan to Baby's defeat. This shows how from training with Shenron, Goku was able to live in peace with his family and friends in both the afterlife and the real world. With his Power Pole in hand, Goku flies off on the Flying Nimbus into the distance and says "Til we meet again, guys." (Source: Wikipedia)
