Heh, poison. Heheh, evil tortue. Anyway, with Saw V being released tonight, might as well have both famous tortue franchises go at it.
In the current state that Saw is in now, I lean more towards Hostel. Besides, Hostel, in some cases, has an evil sense of humor. Especially at the end of Part II. However, if you asked me that when Saws I and II were out and Hostel, I'd say Saw.
