Hi most people call me jh, turtle, or know me as "that handshake collector."
I'm also lazy and don't want to make a proper wiki page. I know too much about MvM, feel free to ask questions and I'll get back to you after 3+ hours with about 5 paragraphs about why the answer to your question is what it is.
I unboxed 834 Mann Co. Supply Munition #103 before getting an unusual (Scout Shako - Searing Plasma) while getting data to update that crate's unbox percentages.
Checkout my TODO list if you want.
