I thought a good chunk of it was pretty mild.. but here are my personal thoughts and opinions. Do not take this as law!
The only thing I think should have had more thought behind saying it regardless of context was Sabat doing the Kami/Popo bit where Kami told Popo he would forever be an indentured servant.
That entire 5 minute skit went a bit too far. When you are using licensed characters you don't own that have an international impact you should know better.
The goku training regimen stuff went a bit too far for warm up too I think.
Chi-chi orgasming to Gohan also felt a bit weird, if only because I grew up to these voices and this shit just... yea it's voicing child/mom incest and I'm not ok with that.
I'll probably be reminded of those voice clips any time I hear dubbed DB, I'll probably be sticking with subbed(I always preferd subs anyway). I think Toei will be worried about other people with similar thoughts.
That was pretty tasteless and I personally don't want characters I've followed most my life linked to stuff like this, even if it was recorded in studio as a joke.
