Okay, so, this probably requires some form of explanation. *clears throat*
Sometime ago, I was pawing about through Vocaloid fan art and came across a picture of Megurine Luka with a really big fish. Actually, she was hitting someone with a really big fish. I must have stared at that image for a good five minutes, just trying to understand why a singer would hit someone with a fish.
The only thing I could think was, "...did Luka join Monty Python and just not tell anybody?"
Of course, that's not what happened. It turns out that Luka has a song she sings about wanting to try eating a tuna and thus the fans have given her a massive bluefin tuna to carry around with her, much like the little octopus that also follows her around.
A little octopus and a giant fish... is anybody else thinking Luka is ready to join the roster of a theme fighting game like Guilty Gear?
Anyway, the idea of Luka being part of a Monty Python sketch just would not be ignored; enjoy.

The two Python sketches featured here are:

Because I seriously do not like that sketch and seeing that character hit with a giant fish makes me smile. X}
