In an action movie, a gang member is being inducted, and he
is instructed to kill their nemesis, a dangerous hit man, with the words, as he
is handed a gun by the gang leader: “Blood in, blood out.”
Then we see the gang inductee kill his target, but getting
blood on his clothes. He returns to the gang leader, telling him he has
accomplished his task, but he got blood on his clothes, and he apologizes for
the evidence trail. But the gang leader takes the bloody clothes and says:
“Like I said: blood in, blood out.” Then he walks into the laundry room, grabs
the brand of detergent the ad is for, pours some in the laundry machine, and
holding up the bloody clothes, he says: “Blood in…” Then he puts the bloody
clothes into the laundry machine. And then we jump cut to him taking the
clothes out of the washing machine, and they’re completely clean, and he points
to them and says: “…Blood out.”
(Seeing the movie John
Wick on HBO made me think of this.)
