Oh, I have. S_D is my after-school treat, probably as healthy for my mind as those Oreos were for my body.
But seriously, I was all, "Hmm, if that's as small a pool as it looks, the shark will be more concerned about getting out of it than it will having a Brunch Wonder, and it's thrashing would probably upset the pirhannas, perhaps stirring up the water too much for them...or if they're really hungry they'll go for the shark so long as Robin keeps still...and there's a big wooden beam between him and the Riddler, so the knives aren't likely to do any permanant damage...and the Riddler hates losing, so if he doesn't manage to hit his target he'll keep throwing and hopefully forget about lighting any fuses or flipping any switches...and even so, if the splashing water causes the circuts to short out, even if the shock is enough to kill Robin most likely Riddler's going with him, and....oh, wait, bondage fan-art. Ha ha!" I need to get out more.
