your fighter/rogue can, in the same world, slide across a table, scissor-kick a waiting orc's spear out of its hands, kick the orc in the forehead, catch the spear in midair, and catch the stumbling orc through the heart with it before he falls while rolling off the table and back into the fray.
(Which you can do according to the rules with a charge attack, assisted by a Jump check to handle the table, and if the Jump succeeds by 5 or more, you rule that the move is so fast and surprising that the orc loses his attack of opportunity for the unarmed attack and you give the fighter/rogue guy a +2 bonus to damage, and maybe even allow sneak-attack damage, in addition to his charging bonus to the attack. The disarm-and-spear bit is either flavor-text, or it's handled next round.)
