This is a terrible pick-up line. First of all, it's too easy to see through. Secondly, they'd be too busy thinking of all the things they could buy if they suddenly had 10 figures worth of cash. Do better.
I don't remember the Beast being such a Spongebob fan. Then again, when you're cursed and alone, I suppose you need something to take your mind off your woes. Shame they watched cartoons instead of putting that massive library to better use.
