DBZ "what if" pairings

After watching DBZ movies with some friends and getting buzzed . This topic came up and we were wondering and talking about them. I like to other people's input on the matter. Some of questions was for example, wound future Trunks and 18 got along, and how didn't Goku and Bulma hook up again?

hmmm....I don't think this thread should be here in Serious Discussion.

Whoops! I thought all of the types of forums you got was from the little tap up top. My Bad.

yeah why goku didn't end up with bulma doesn't make sense goku is more or less the same type of character as luffy
goku made a promise to marry chichi cause he thought marriage was food
