gasp I’ve been noticed? Wow thats a first for me. Though I don’t know about that matchup. Her north refers to Canada, whereas my north isn’t very north at all, considering its only the north shore of Long Island. But I’ll take it anyways!
Maybe, but she’s around Baltimore now. 
David, God of Frogs vs. St. Urho.
Excellent find F_X.
Arachnid Love vs. SpiderWoman.
David, God of Frogs vs. Da Toad. Then again, maybe Da Toad is one of David’s disciples…

(Spoz would have done this himself when I told him about it, but he’s too lazy… so I said I’d do it)
