Did Samurai Jack ever get home?
I think he actually sort of did, or at least, the series did have some kind of grand finale where he fought Aku (?) in the end, and maybe he went back home, or maybe he did go home and then said, heroically, "No. My place is in the future. There's aliens and weird shit that needs my help.", or something like that.
I forgot the details, but there was some kind of closure, IIRC.
