I dressed up as Steve for Halloween

He... Is Steve.

Now that you mention it the resemblance is uncanny

uncanny resemblance is tight!

YOU... are Steve

I,

AM STEEEEEVE

resemblance uncanny

YO EVERYONE, THIS GUY OVER THERE... is steve.

Wouldn't that make you Jack Black?

Which means Bowser?
(yes Jack Black voiced Bowser in the Mario movie)

nice costume
but what is this fake ahh diamond sword?

I have this one that I actually used on Halloween, but it's uncomfortable to carry since it's 2-inch thick plastic. This picture of me was from a relative's birthday/costume party

ahhh
alr :)
