My opening scene idea: A busy cafe on an alien world, robotic waiters flying around, tentacles, blue people, some humanoids. We pan in to a pair of Ferengi males in the corner talking closely. Conspiring.
"You ready?" "Yes, let's do it"
They kiss passionately and then one of them jumps up the table, fires a disrupter into the ceiling and yells:
"Everyone put their latinum on the table! Any of you fucking targs move and I'll vapourize every motherfucking last one of you!"
