Buuuut she's probably not a threat to you, Luke. Not unless you kidnapped a princess. That said, Justin Forever is arguably superior to Batman Forever, and is definitely better that Duke Nukem Forever, so... Actually, that doesn't tell us much. Nonetheless, Justin is an acceptable choice.
Tensaided is quoting Rocky IV (or, at least, we can only hope that's what he's doing). I haven't seen it, or indeed any of the Rocky movies, but it's my understanding that Rocky IV ended the cold war. Good job, Rocky! You're a peace making machine!
Seriously, though, I totally need to watch Rocky sometime.
Speaking of things being referenced, panel six is totally referencing Azumanga Daioh. I mean, Dragon Ball Z. Sorry, I get those two confused.
