Sirius a Slytherin? Convince me!

As for all four of MWPP being in different houses, and Lupin being in
Ravenclaw, in POA, when Lupin is giving Harry dementer lessons, he
brings butterbeer for Harry and says "To a Gryffindor vicotry"
(against Ravenclaw).  I doubt that he would drink to a victory against
his own old house.

Plus, in OOTP, Lupin says that he was given the Prefect badge so he
could have some influence over his friends.  It implies that he chosen
for the badge OVER his friends so he could exert influence over them.
 As only one of them can chosen from each house, I belive that they
were all in the same house.  Plus, I don't think Sirius needed the
others influence to know that his family was crazy for their pureblood
mania, James just gave Sirius a place to stay afte he officially left
home for good.
