Quoted from DarthXaos:
Lyman's lament when using the flipper code is not supposed to add to the scoring, yet in multiplayer games it will add to the 2nd player's scoring (but not the first) as if they had earned it legitimately.
Not a bug -- this is a great feature! When you're playing with friends, it becomes a contest to see who can get a decent score *while avoiding the scoop* for as long as possible, so that you get the +25 bonus X, and avoid the +0! Super fun to be forced to play a different strategy, especially while getting taunted by Lyman while doing so.
