how about Future Trunks accidentally goes back in time too far for whatever reason, and ends up meeting (see: getting robbed by) the Desert Bandit Yamcha? Trunks thinks that he would make a much better boyfriend than a thief, and hopes that bringing him along for the ride won't mess up the time space continuum. Much.
