Considering that the gang consists of a girl who tricked Goku into helping her get Dragon Balls so she could get a boyfriend, an armed robber, a pig who used his shapeshifting powers to kidnap a bunch of teenage girls, a loser who trained with Master Roshi just so he could beat up bullies, a floating midget who cheated at the World Martial Arts Tournament, a three-eyed guy who tried to viciously beat up Goku and idolized a murderer, and a genocidal alien maniac reincarnated who tried to murder Goku, it's not that weird.
