A very weird opening

Here, my opponent played, in my opinion, a very strange opening even by unorthodox standards.  I won this, but only because he played very bad moves.  I probably made some dubious moves too, but I believe I out-played him here.

I could be wrong, though.  What do you guys think?

3...Nxa6 would take care of his bishop without endangering your rook.

I like how you were able to ignore the threats he made of his own (such as taking your rook on h8) and go in for your own mate 

Why not on move 3 you just capture the bishop with Nxa6 and your bishop still protects the b7 pawn.

Uh..........I overlooked that.......

Wow.......

How bout this

All black would do is move there rook to B8 and now they gain a tempo and whitte has to retreat their bishop
